The vote for the creation of this newsgroup passed on 28th July 1994 with 148:36, it was effectively created on 4th august 1994. It was the idea of Marco Vieth and David Long.
This unmoderated newsgroup comp.sys.amstrad.8bit is open to discussions about the Z80 Amstrad computers : CPC (464, 664, 6128, 464+, 6128+), GX4000, PCW (8256, 8512, 9256, 9512, 9512+, 10, 16), NC100/150/200 and PDA600.
Appropriate topics include, but are not limited to :
- CPC, GX4000, PCW, NC, PDA hardware and software, - emulators, - specific Amstrad CP/M files, overlays... - ads for selling/buying the relative hardware and software.
The only topic that is excluded :
discussion of Amstrad PC-compatible (1512, 1640, 2x86, 3x86 and others Amstrad compatible I don't know) because these computers are really compatible, so comp.sys.ibm.pc.* newsgroups must be used, especially comp.sys.ibm.pc.classic
For questions about these PC see http://web.ukonline.co.uk/cliff.lawson and http://www.seasip.info/AmstradXT
For easier reading and filtering, please use the following tags at the start of your subject line :
- announce posts : [announce] - unrelated topic : [i] - for buying items : [want to buy] - for selling items : [want so sell] - for post in another language : [french], [german], etc..., but put a short summary in english to not ignore people who dont understand your language, also you will get much more help if more people can read your post.
Z - Alan Michael Sugar TRADing
Alan Michael Sugar created his company, and called it using his name : Alan Michael Sugar TRADing, that's Amstrad.
More on Amstrad company later.
A - Amstrad CPC
A0) Amstrad CPC(+), KC compact and GX 4000 presentation 06/30/2003
They use the Zilog Z80A processor which speed is 4.00MHz. From SOFT968 "The system centres round the Z80A with a 4.00MHz clock" Later it states that "Accesses to memory are synchronised with the video logic, constrained to occur on microsecond boundaries. This has the effect of stretching each Z80 machine cycle to be a multiple of 4 time states (clock cycles) In practice,this alters the instruction timing so that the effective clock rate is approximately 3.3MHz"
Amstrad made the following CPC systems :
- 1) CPC 464 (Arnold 1), - 2) CPC 664 (Arnold 2), - 3) CPC 6128 (Arnold 3), there was also a CPC6128 cost down (Arnold 4 which was identical in operation to the original 6128 but had a new PCB and ASIC that reduced the board size and chip count to a mere fraction of the original size. If you open up a 6128 and the board fills the entire space you've got one of the originals. If you open one up and the board only occupies about 1/4 to 1/3 of the available space with a LOT of surrounding fresh air then you've got an Arnold 4. - 4) CPC 464+ (Arnold 5), - 5) CPC 6128+ (Arnold 6), - 6) GX 4000, the Amstrad 8 bit console.
The CPC+ and GX 4000 have enhanced graphics and sound (DMA), colour palette of 4096, hardware sprites, hardware scrolling, and used 128 Ko to 512 Ko carts.
Amstrad used CRTC (Cathodic Ray Tube Controller) from different manufacturers, which worked the same in the main, but do have many different characteristics. This is the reason why a demo designed for CRTC type 1, may not display correctly (or even at all), on a CRTC type 0 :
- CRTC 0 : chipset HD6845S, - CRTC 1 : chipset UM6845R, - CRTC 2 : chipset MC6845, - CRTC 3 : CPC+ Asic, - CRTC 4 : ?
The KC compact (KC mean KleinComputer = little computer) is a clone of the Amstrad CPC. It was made by VEB Mikroelectronik in East Germany (the old DDR) in 1989. It was made the year before the Berlin wall came down, and ceased production soon after.
The KC compact is 95% compatible to the CPC. The functions of the Gate-Array are simulated by TTL-Logic and a Zilog Z8536 CIO. The ROMs are a patched English CPC6128 Operating system ROM (includes setup code for the Z8536) and a unpatched Locomotive BASIC v1.1 rom.
The only incompatibility lies with the interrupt generation mechanism. Any program that relies on exact interrupt generation behaviour may fail to work.
In some respects, the KC compact is actually more powerful than the CPC, because the interrupt frequency can be programmed, in theory the resolution could be reprogrammed, and the colour palette changed (replacing the colour rom). More details are available at http://andercheran.aiind.upv.es/~amstrad
If you can read french and want to learn more about Amstrad CPC history, you should order the excellent book "Ces ordinateurs sont dangereux" by François Quentin (fquentin club-internet.fr) for 25 Euros (postage included, send an international postal order by going to your post office) to :

b) WinAPE comes with a ROM image called CPCDOS. Simply select the ROM (probably best below AMSDOS in ROM 6), then you can use |DOS, |DOS.IN, |DOS.OUT, |CD c) inject them in a .DSK file with CPCFS (see A1.2.4) :
- create an empty .DSK : CPCFS -nd empty.dsk (you can omit the .dsk) - inject files : CPCFS empty -mp *.* (the files must be in the current directory, the DSK can be somewhere else)
To extract files from a .DSK : CPCFS image.dsk -mg *.*
XTI by Pierre Guerrier can also put amsdos files into a DSK. Note that there are MAC and Amiga ports of XTI.
A2.4.3) How to run programs with a CPC or emulator ?
Type CAT to get the directory of the disk, mostly programs are run with a BASIC loader, so looks for *.BAS, then type RUN"name.BAS" (.BAS can be omitted). If there isn't a basic loader, run the .BINary program directly : type RUN"name.BIN" (.BIN can be omitted).
Some disks doesn't have a real directory, and must be launched with the CP/M command : |CPM.
For running tapes on a real CPC, type RUN", the CPC will launch the first program on the tape.
A2.4.4) How to format a disk 01/03/2003
On a CPC, use the formatting utility on your CP/M disk (diskit) or the following basic program :

A3.1.1) 3" drive on PC (part one) 10/22/2002
- A working solution on http://www.fvempel.nl/3pc.html
A3.1.2) 3" drive on PC (part two) 01/11/2000
Porting files across from CPC to PC is easy, at least, if you have a DDI-1 disk drive ! You need to follow exactly these instructions. As is usual with things like this, you do everything entirely at your own risk. I have done this on my own PC without damaging it, but cannot guarantee that it will work with yours. If you do damage your computer, it is YOUR FAULT.
Note of the FAQ keeper, I have a report of someone trying out the following instructions, who had his controller burnt, and another whose 3" drive died, so beware.
These instructions only apply to the DDI-1 package. They MAY work with the FD1 3" second drive, and will definitely NOT work with the internal drives on 6128s, 664s, and 6128+s.
Install 22DISK! You will need to tell it you have no A: drive, and that B: is a 360K drive, physical unit 0, on the Primary adapter, with step-rate of 12 milli-seconds. You will also need the CPMDISKS.DEF file from CPCEMU.
0 Install 22DISK with CPMDISKS.DEF coming with CPCEMU or the one from EURODEF.ZIP
1 open your PC, following all usual precautions such as turning off the power and discharging any static electricity on your body!
2 Unplug any floppy drives. This step is important. (See note 1)
3 Find the connector that is meant for the B: drive. (It is probably on the same cable as the connector for the A: drive. The A: connector has a twist in it. The B: connector is the other one!)
4 Plug it into your DDI-1 drive unit. You may have to file the keyway on the connector off. (Different PCs have different keyways on their connectors, so you may not have to attack it with a file. So much for standardisation!)
5 Turn the DDI-1 drive on first, then the PC. When it does the Power-on test, press DEL to enter the setup menu (you have got an AMI BIOS haven't you?). Tell it you have no A: drive and a 360K 5.25" B: drive. (See note 2)
6 Use 22DISK to read (not under OS/2 or windows 95), write and format your 3" disks to your heart's content ! You could also use ANADISK I suppose.
7 When you've finished, restore the machine its original state. As well as using CPC disks, you'll probably be able to use Spectrum 3 disks if you have an appropriate CPMDISKS.DEF. If of course you want to use Speccy disks...
Note 1 : Amstrad's disk drive is reasonably standard, but not quite! When you install it, it claims to be both your physical drive 0 and physical drive 1. As such, if you expect it to be just drive 1 (B:), and leave unit 0 (A:) still plugged in, it will promptly ram the heads of unit 0 hard against the end stop, promptly trashing your unit 0. I found this the hard way, and had to buy a new 3.5" floppy drive.
Note 2 : If you don't have an AMI BIOS, then this will be different. You may have to run a program from a system disk which came with your computer.
The pin-outs of the 3" drive are _identical_ to the ones of a 5.25" drive - it will just plug in. It's a long time since I was inside my Einstein, but I'm pretty sure that drive is a 40track SS unit - what a PC would call a 180K drive. Things like the Disk Change line may be different, but if you set up your PC to ignore that (and possibly tell it it's a 360K drive), you should be OK.
I've used a 3" drive (actually a Double-sided model) with an original IBM XT in this way.
A reply to the last two paragraphs :
It actually depends on the type of 3" drive. Some of them had a 34 way connector like the IBM PC 5.25 " drive (i.e. PCB gold plated edge connector) and are compatible. Genuine Amstrad drives on the other hand have a 26-way PCB header which contains all the useful signals, although some have been removed.
I remember, that the 34 way connectors are only nearly compatible. In those days around 1985, I connected a CPC 464 External drive to another CPM computer with standard 5.25" drives like the PC-drives. It was necessary to swap the lines since the pin numbering was mirrored compared to the standard.
I also think that the exact layout depends on the version of the computer (CPC 464/664/6128). So be careful and do not ruin your hardware by building sh circuits! (It shouldn't be very difficult to verify which are the GND-lines )
A complement to this reply
The Amstrad and PC disk connections are as follows:
26 pin Amstrad disk drive:
Index 2 * * 1 GND DS0 4 * * 3 GND DS1 6 * * 5 GND Motor 8 * * 7 GND Dirn 10 * * 9 GND Step 12 * * 11 GND Wdata 14 * * 13 GND Wenable 16 * * 15 GND Track0 18 * * 16 GND WProt 20 * * 19 GND Rdata 22 * * 21 GND Side 24 * * 23 GND N.C ? 26 * * 25 GND
34 pin Standard disk drive:
Head Load 2 * * 1 GND In Use ? 4 * * 3 GND DS3 6 * * 5 GND Index 8 * * 7 GND DS0 10 * * 9 GND DS1 12 * * 11 GND DS2 14 * * 13 GND Motor 16 * * 15 GND Dirn 18 * * 17 GND Step 20 * * 19 GND Wdata 22 * * 21 GND Wenable 24 * * 23 GND Track0 26 * * 25 GND WProt 28 * * 27 GND Rdata 30 * * 29 GND Side 32 * * 31 GND N.C. ? 34 * * 33 GND
Note that on the Amstrad drive, DS3 and DS2 are missing.
The pins marked with a ? may have been redefined on some drives (e.g. on high density PC drives, one of them is used to change the drive current - I can't remember which now), also on very old single sided drives, the Side signal used to be used to reset the drive. If you are using a 34 way connector drive in an Amstrad, you may want to hard wire Head Load to be permanently enabled (if it is used - not all drives do).
A3.1.3) 3" drive on PC (part three) 02/17/98
Here is other information by Juan Perez Delgado, as I know nothing of hardware, be cautious. This doesn't apply for Schneider drives.
1. Read all first
2. Then you open your PC, and unplug and take off the cable that goes from the FD controller to the FD drives. The cable looks something like this: (including the twist between the B: and A: connectors) (ctlr = Floppy Disc Controller)
to FD ctler to B: drive to A: drive /-\ /-\ /-\ 2 -|---------|-|---------|-|2 4 -|---------|-|---------|-|4 6 -|---------|-|---------|-|6 8 -|---------|-|---------|-|8 10-|---------|-|-\ /----|-|10 ) 16 of ctler, A: thinks it is 10 12-|---------|-|- \/ ----|-|12 ) 14 of ctler, A: thinks it is 12 14-|---------|-|- /\ ----|-|14 ) 12 of ctler, A: thinks it is 14 16-|---------|-|-/ \----|-|16 ) 10 of ctler, A: thinks it is 16 18-|---------|-|---------|-|18 20-|---------|-|---------|-|20 22-|---------|-|---------|-|22 24-|---------|-|---------|-|24 26-|---------|-|---------|-|26 28-|---------|-|---------|-|28 30-|---------|-|---------|-|30 32-|---------|-|---------|-|32 34-|---------|-|---------|-|34 \-/ \-/ \-/
3. Using a screwdriver and a cutter I reordered the wires that go to the A: drive (I left some of them not connected):
to FD ctler. to B: drive to A: drive /-\ /-\ 2 -|---------|-|------- You can see that signals 4 -|---------|-|------- 2,4,6,10(16 from the ctler) 6 -|---------|-|------- are not used. 8 -|---------|-|---------\ 10-|---------|-|-\ /-nc \-|-| 2 (connected to ctler pin 8) 12-|---------|-|- \/ -------|-| 4 14-|---------|-|- /\ -------|-| 6 16-|---------|-|-/ \-------|-| 8 18-|---------|-|------------|-| 10 20-|---------|-|------------|-| 12 22-|---------|-|------------|-| 14 24-|---------|-|------------|-| 16 26-|---------|-|------------|-| 18 28-|---------|-|------------|-| 20 30-|---------|-|------------|-| 22 32-|---------|-|------------|-| 24 34-|---------|-|------------|-| 26 \-/ \-/ |-| 28 |-| 30 |-| 32 |-| 34 \-/
Of course, odd pins must be connected to wires of ground (odd pins in the drive with odd pins in the ctler, doesn't matter the number).
4. Next, you open the CPC6128, and get the 3"FD, unplug only the cable that comes from the controller (the one in the 26-pin connector).
5. Plug-in the cable you have 'build' in step 3 to the FD cntler (as it was before you disconnected it), and connect the CPC 3"FD to the connector whose wires you have reordered. As the connector is 34 pin wide, and the drive is 26-pin, there will be a side not connected (corresponding to pins 28 to 34).
Now you have the controller cable from the PC controller connected to the 3" drive. I think you can still connect another driver to the other free connector, but I didn't try it because I read some people have burned its controller doing similar things. You leave the power cable of the 3" drive connected to the CPC, as it was before.
6. Now, you switch on your CPC (monitor, then keyboard). The FD will start running continuously.
7. Now, you switch on your PC. If all is Ok, nothing should burn :), and the 3" FD will stop running. Then in the bios setup you tell you have a 360Kb 5.25" drive A. You boot the PC again if needed.
8. In order to use with CPDRead, you must set your drive (cpdread.cfg) as a 360Ko drive with 360Ko disks, and you must set #STEP to 2)
#STEP set to 1 worked for somebody else.
A3.2.1) 3,5" or 5,25" drive on CPC 06/29/98
See A5.2 after installing your new drive.
You can use a 3.5" or 5.25" drive on a CPC. You have to take care about the cabling, as some 6128s use a 36 pin port and the drive only has 34. A normal PC floppy cable (5 connector) can be used to connect drives, although some connectors may need changing. The six problems which can arrive are:
- The drive has no ready signal. That is true for some older PC drives. In this case, forget it, if you are not able to solder some IC's to simulate the signal.
- You can only use one side of the disk (180k). If you want to use both sides, you have to solder in a switch, or get another DOS (Vortex XDOS or Dobbertin X-DDOS), the best DOS is ParaDOS.
- High-density drives have a hi/lo signal not present on CPCs which may cause problems, it is probably best to use older 720k drives.
- Some 5.25" drives, namely 720k QD drives, may cause problems, however these are not very common and so shouldn't be a cause for concern.
- Drives may not work properly on the CPC by giving read errors and seek errors, etc. The first thing to do in this event is to clean the edge connector on the CPC with some IPA (head cleaner fluid), and then clean the drive heads in the same way if necessary.
- The jumper setting on the drive is wrong. On older 5.25" drives you may find that they have been set to Drive 0 (DS0), in which case you need to set the drive to drive 1 (DS1) or use a PC drive cable which has a twist in it.
To copy disks from 3" in drive A to 3.5"/5.25" in drive B
the best method is to use Disckit2/3 that comes with CP/M, depending on
which version you have. If Disckit3 doesn't work, Procopy can tackle most disks, and runs from drive B so you can copy it across to your CPC fairly easily. You can read the CPC disks on the PC with 22DISK from Sydex, or Ulrich Doewich's CPDRead, see A1.2.6 and A1.2.8.
The following diagram is a pin table comparing a modern 1.44Mb 3.5" drive to the drive B connector on a CPC, which you may find useful. Note that although the CPC connector is numbered backward, it is still directly compatible.
1.44Mb 3.5" drive: CPC drive B connector
All odd pins: Ground -------------> All even pins: Ground 2: Hi/lo density -----------------> 33: N/C 4: N/C ---------------------------> 31: N/C 6: N/C ---------------------------> 29: N/C 8: Index -------------------------> 27: Index 10: Motor enable A ---------------> 25: N/C 12: Drive select B ---------------> 23: Drive select 1 (B) 14: Drive select A ---------------> 21: N/C 16: Motor Enable B ---------------> 19: Motor On 18: Direction select -------------> 17: Direction Select 20: Head Step --------------------> 15: Step 22: Write data -------------------> 13: Write data 24: Write gate -------------------> 11: Write gate 26: Track 00 ---------------------> 9: Track 0 28: Write protect ----------------> 7: Write protect 30: Read data --------------------> 5: Read data 32: Head select ------------------> 3: Side 1 select 34: Disk change ------------------> 1: Ready
A detailed guide more specific to 5.25" drives can be found at the All Things CPC website, and there is also information at the other CPC sites, see A2.2.
A3.2.2) 3,5" or 5,25" drive on CPC+ (by Simon Matthews)
See A5.2 after installing your new drive.
Adding a 3.5" drive to the CPC 6128 was a doddle - 34 way card edge connector on one end, 34 way IDC on the other end and you were away.
The numbering on the pins was pretty easy, too. Looking at the connector from the BACK of the machine, Pins 1 to 33 (odd) ran from left to right along the bottom, pins 2 to 34 (even) ran from left to right along the top. All of the top pins were grounded, and pin 1 (bottom left) was the READY line, which by convention would be denoted by the "stripe" of the ribbon cable. At the other end, a simple IDC plug connected to the external drive, usually with the "stripe" nearest to the power connector.
The problem with the CPC+ is that the connector on the back of the computer is 36-way, not 34 and is numbered back to front as well. So, looking at the connector from the BACK of the machine again, pins 1 to 35 (odd) ran from RIGHT TO LEFT on the top of the connector, and pins 2 to 36 (even) ran from RIGHT TO LEFT on the bottom of the connector. Again, all of the even pins were grounded. Here's where it gets tricky...
This time, pin 33 is READY, pin 31 is SIDE 1 SELECT all the way to pin 7 which is INDEX. In other words, the lines are in the same order, but different pin numbers. It all sounds quite hectic, but it's easy to sort out in practice.
Firstly, take a length of 34-way ribbon cable and crimp the 34-way IDC connector on as usual. At the other end, peel away the cable on the other side of the "stripe" for a few centimetres. Now place this cable in the 36way Amphenol connector so that the stripe corresponds to pin 33; in other words, make sure the LEFTMOST 3 blades are left empty. The other edge of the cable should be lying on the RIGHTMOST blade, with the wire you peeled away not connected to anything.
|||||||||||||||||||||||||||||||||| "stripe" --->|||||||34 WAY RIBBON CABLE|||||||| |||||||||||||||||||||||||||||||||| ||||||||||||||||||||||||||||||||| \ ||||||||||||||||||||||||||||||||| \ <--- Peel away ||||||||||||||||||||||||||||||||| Goes to pin 33->||||||||||||||||||||||||||||||||| <--- Goes to pin 1 ||||||||||||||||||||||||||||||||| pin 35 --------------------------------------- pin 1 \ / \ 36 WAY AMPHENOL CONNECTOR / pin 36 ------------------------------------- pin 2
* LEFTMOST 3 pins (36,35,34) NOT CONNECTED *
Double check all is Ok, then crimp together. Now you can test the cable on your external drive. If the drive is unresponsive, or just spins constantly, try plugging the IDC cable in the other way around; most drives want the "stripe" nearest to the power connector, but a few want it the other way around.
I know it sounds complex, but have a look at the pin-out diagrams and it's not too bad.
A3.3) parallel cable 06/08/2001
The CPCEMU emulator has documentation on how to make such a cable yourself and includes utilities for both the PC and CPC that allow two-way communication and file transfer. However CPCPARA.BAS supplied in this package can extract files from CPC disk drives, not those saved on cassette tape. For files on tape, see A1.2.14.
following line to be removed on next FAQ See A126.96.36.199 for getting this cable in France.
If you have a problem with PCPARA.BAS, coming with CPCEMU, load the program into the emulator (put it in the TAPE directory) and save it as an ascii file with this command : SAVE"PCPARA.BAS",A or use SEND2
A3.4) RS 232 & RS 422
Neither the CPC nor the PCW have a RS 232. You can buy it, you then just need a communication program on PC and CPC/PCW and a null modem cable to exchange files between the computers.

A5) Hardware problems
A5.1) Internal drive 07/22/2000
If you have the error : 'disk missing', the drive belt should be the problem. The best solution is to come with your old belt in an electronics shop and see the available belts. You should look for one with the dimensions 72mm x 3 mm x 0.5 mm (although I believe it is OK to use belts in the length range of 69-72 mm long and either 3 or 4mm wide).
You can find belts at Paris (75011), reference Koenig 7093.00 at Espace Composants Electronique, 66 rue de Montreuil, métro Nation, phone 01 43 72 30 64, fax 01 43 72 30 67 (http://www.ibcfrance.fr)
Cibotronic at Paris (France) used to sell them, but they don't have them anymore. The reference was MASTER type CR 4092, dimensions 71.0 x 0.6 x 2.8 mm.
An U.K. address : Andre Howard at 65 Altyre Way, Beckenham, Kent BR3 3ED. Price is #2.25 (UK pounds) including P&P.

For Germany, see A188.8.131.52 and A184.108.40.206
Now it is time to change the belt of an Amstrad CPC 6128/6128+ : - open the CPC by unscrewing the screws at the back of the CPC, without disconnecting anything. For a CPC+ there are screws and 3 clips, - unscrew the drive from the CPC, - disconnect the 2 cables (data and electricity), - if you have a CPC+, get out the drive from its metallic place, there are 4 screws and you have to push the drive, - put the drive to let you see the green electronic card, - unscrew the card from the drive, - disconnect the items which goes from the card to the drive to let you lift enough the card and see the belt (you wont be able to detach completely the card from the drive), - remove the belt with your fingers or a screwdriver. In all cases, keep always the drive with the head down, or a nail will fall. It is used for the detection of write protection. - buy a new belt (see above), - put the new belt, reconnect all items, screw again the green electronic card, reconnect the drive to the CPC, close the CPC.
The other possibility is a fault with the index hole detection. As well as the large shutter on a 3" disc, there is also a smaller one through which the disc drive can watch for the index hole to go past. There is a LED and an associated detector that watch for this, and if either has gone wrong or got covered in dust you may get disc missing messages.
A5.2) External drive 05/15/99
See A3.2.1 and A3.2.2 for adding a 5,25" or 3,5" drive to your CPC. Then, when the drive is installed, you can't format your disk to the full 720 Ko unless you have a ROM box and another operating system such as RoDOS, ROMDOS (not CPC+ compatible) or ParaDOS (the best one). Parados recognise all ROMDOS formats and can replace ROM slot 7 (Amsdos).
The place to go for CPC spares is (coincidentally) a company called CPC Spares in United Kingdom, at +44 1772 654477.
There are 3 Gate Array, two types being used on 464 (a very old cpc uses 400007, the newer ones have 400010).
The AM40007 is the type used in most CPC464's and they should be available from CPC Ltd. +44 1772 654455. They're gonna be expensive though, probably about 25-35 pounds.
A6) How can I help the Amstrad world ?
A6.1) Updating the FAQ
By sending corrections, modifications, new informations for this FAQ to roussin noos.fr
A6.2) Commercial games becoming freeware 07/31/2004
If you know addresses of authors who wrote programs on CPC/PCW, send me their address, I will write them to ask the persmission for letting their games to become freeware or shareware (they still will retain the copyright, even after all these years).
See http://genesis8.free.fr/gamecal.php for the games that already became freeware, or almost freeware (authors stating that they don't care for the distribution of their games).
A6.3) Adding files to ftp.lip6.fr 04/15/2001
You can send me your latest production. As there is no upload directory on lip6, you will need to email your programs to roussin noos.fr, or send them to ftp.nvg.ntnu.no/pub/cpc/incoming, I will then put it on ftp://ftp.lip6.fr/pub/amstrad

A18.104.22.168) Futur's 10/31/99
Futur's is a french group, they do many things. They bring you the Soundplayer (a better Digiblaster). It connects on the printer port. The Soundplayer is used by Protracker and Digitracker. You can do it yourself for about 5 euros of electronic components. The electronic plan is in the paper zine Quasar issue 9, see A9.1.3. With this little marvellous thing, you can have 8bit samples, instead of 4bit samples. The SoundPlayer+ is a better SoundPlayer, which can include Virtual Net 96 (see A10.5) for a bit more more, or which can use a CPC+ port instead of the normal CPC printer port.
The SoundPlayer II now exists. It connects on the expansion port and permits to make mono 8 bits/22KHz digitalized sound. It offers one more port to connect a second Soundplayer (for stereo) or to free the printer port.
For ordering a SoundPlayer+ or 2, see A9.1.3

A10) Additional hardware
For using older additional hardware on a CPC+, you will need an adaptor called a widget, as connections are not the same. They use the same connectors as german CPC (Schneider). All hardware should work with this adaptor, except the standard multiface, see A10.2 (06/09/97)
Look A6.4) for a list of hardware made on CPC.
A10.1) Hard disks (no more produced)
A10.1.1) MFM hard drive
- a Dobbertin MFM interface with 20 MB HD, - in the very early years a Vortex Filecard with 20 MB MFM HD.
A10.1.2) AT IDE hard drive
A10.1.2.1) GIDE 11/08/2004
The GIDE is a generic Z80 device that allows easy connection of any AT (16 bit) IDE hard drive to a Z80 computer. If your Z80 is socketed, you simply unplug it, plug the GIDE into the Z80 socket, and plug the Z80 into the GIDE. You need to write your own driver
Gide doesnt exist for Amstrad CPC, but you will find informations about the GIDE for PCW on : - All about the GIDE interface - KC-Club.GIDE-Interface.
A10.1.2.2) IDE Drives (by RAM7)
It uses an ISA IDE controler and an adaptator card wich plugs in the expansion connector. It will be able to use IDE hard drives, CDROM (certainly) and disk drives (1.44 Mo). Not available for the moment.
A10.2) Multiface II
A useful add-on, connected to the expansion port, its primary use is to make snapshots, exactly like the emulators. See A1.2.7, an utility to transform multiface snapshot to emulators snapshot.
There is a special multiface for the CPC+, standard multiface doesn't work on a plus, even with a widget. (06/09/97)
A10.3.1) ROMCARD and RAMCARD 10/31/99
Francisco DOS SANTOS 123 boulevard Strasbourg 94130 NOGENT SUR MARNE FRANCE email : ram7 mail.dotcom.fr (no reply or very slow, best way is to use snail mail)
The ROMCARD is a ROM box with 4 available slots which accepts 16 Ko (27128) or 32 Ko (27256 or 27C256) EPROM for a maximum of 128 Ko (so better use 32 Ko as there are only 4 slots). Other ROMCARDs can be put in parallel, to add another 128 Ko of ROMs each time.
The RAMCARD is a ROMCARD that uses 128 Ko of RAM instead of ROM.
the ramcard, a rombox using RAM
A10.3.2) Inicron ROM-RAM-BOX 04/15/2001
The RRB is a ROM box that doesn't need EPROMs. Up to 32 EPROMs can be simulated in the 512Kb big RAM (if build the enhanced RRB). Additional to this you can use a normal EPROM from 8-64Kb in a normal EPROM socket. Go at http://www.inicron.de or get ftp://ftp.lip6.fr/pub/amstrad/roms/rrb.zip
A10.4) SoundPlayer 1 and 2
See A126.96.36.199) and A9.1.3)
A10.5) Network 10/31/99
A10.5.1) Virtual Net 96 (VN96)
Virtual net 96, a network for Amstrad CPC, made by germans, look at (english and german page) :
Get ftp://ftp.lip6.fr/pub/amstrad/misc/vn96eng.lzh (or ger instead of eng) for information about VN96.
A10.5.2) Multi-IO card 05/30/2003
VN96 doesn't work on a CPC+, but Futur's (see A188.8.131.52) has a plan for a VN96 card for CPC+, which will work of course on plain CPC. But the multi-IO card is more than a VN96 card, it has a standard parallel port where you will be able to connect all parallel devices such as a printer or a ZIP drive when a driver will be ready. The price will be about 15 euros.
A10.6) Future OS 05/31/2003
Future OS is a new operating system for Amstrad CPC that needs a rombox or a rambox, Future OS is more powerful than amsdos, but amsdos and CP/M programs must be adapted before using them under Future OS (they can even work faster). Type |OS or |FDESK to launch Future OS. For more information, go http://www.FutureOS.de You can use it on emulators like Caprice (install ROMs A B C D in slots 10 to 13) or WinAPE 2.0a4 (doesnt work with WinAPE 2.0a5).
A10.7) Memory extension
A10.7.1) 256 Kb to 2 Mb MemCard (by RAM7) 05/30/2003
For 6128 and 6128+, it's compatible with Dk'tronics memory extensions, it plugs on the expansion connector. It uses the same memory managing of the 6128 second 64 Ko bank. It comes with 4 slots of static RAM (128 Kb or 512 Kb). For more information, see A10.3
Beware the 256 Kb and 512 Kb models use 128 Kb RAM, the 1 and 2 Mo use 512 Kb RAM. An extra cable is also needed.
the memcard, a memory extension compatible with Dktronics
A10.7.2) Inicron RAM-BOX 04/24/2000
A 512 Ko RAM extension for Amstrad CPC by Inicron, get ftp://ftp.lip6.fr/pub/amstrad/misc/rambox.zip or go at http://www.inicron.de
A10.8) Card Tridge (by RAM7) 10/31/99
The Card Tridge can read, copy and store Amstrad CPC+ cartridges with its 512 Ko of RAM). For more information see A10.3
A10.9) CPC ISA 03/26/2005
Connect ISA cards on your CPC by Siou (siou free.fr) : http://siou.free.fr
As 26th March 2005, playing adlib music (.SA2 files) works with a Sound Blaster, and low level working of hard disks too, file system must still be done.
the CPC ISA card
A10.10) Amstrad MP1 and MP2 10/27/2000
Amstrad MP1 and MP2 replace the CPC monitor alimentation and permits to use the television (SCART connector) for the video output (MP1 for 464, MP2 for 664/6128). You can also send the video signal on a PC which has
a tuner card.
The MP1 does not provide the 12V connector the 664/6128 needs to power the floppy disk drive. So you can use a 664/6128 with a MP1 but you cant use the floppy, or you need an external power supply.
A10.11) CD-ROM 05/12/2003
For several years people thought that the CPC version of the Codemasters CD-ROM (using a domestic CD player and a special interface to convert the audio signal into something suitable for Arnold) didnt exist. In fact, the developper (The Oliver Twins) of product acknowledged that it did exist, for more informations : http://andercheran.aiind.upv.es/~amstrad/docs/audiocd2.html
A10.12) Mouse 08/06/2000
You cant use a PC mouse (serial or PS/2). There are Amstrad CPC mouses, but few programs uses them (Advanced OCP art studio) :
- AMX mouse (the most common), - GENIUS mouse, - DATEL mouse.
A11) Upcoming Meetings
B - Amstrad Notepad (NC100/150/200)
B0) NC 100/150/200 presentation 08/06/2000
The Notepad is Amstrad's idea of a simple word processor. It is NOT a PC-compatible and is NOT the PenPad PDA.
The NC100, launched in september 1992, is about A4 size with a LCD screen (80 car. x 8 lines), nearly full size keyboard, a PCMCIA memory card slot on the left side, four coloured keys, 64 Kb of RAM. It features a word processor, word spell checker, address book, calculator, diary, clock, alarms and BBC basic. There are a serial and parallel ports.
The NC200, launched in october 1993, has a fold-down LCD screen (80 car. x 16 lines), a 3.5" disk drive, 128 Kb of RAM, new software (spreadsheet and graphics, games).
The NC150, launched in april 1993, has the look of the NC100 but the NC200 software, 128 Kb of RAM too, and the possibility to connect a 3,5 drive. It exists only in french and italian versions.
B1.1) M.E.S.S. 06/09/2004
B1.2) NC100EM 03/17/2001
NC100EM by Russell Marks for Linux (svgalib, X, tty) and MSDOS. It supports both the ROM software and ZCN, a free CP/M 2.2 clone. Get it at http://rus.members.beeb.net
B2) How can I buy one ? 10/27/2000
Unfortunately, Tandy finally stopped selling them in November 1996. The best way to buy one now is probably second-hand ads in national computer magazines, "for sale" newsgroups or auctions sites like http://www.ebay.com
B3) What peripherals can I use ?
The Notepads have standard Centronics parallel ports and RS232 9-pin serial ports. The system has drivers for 9 and 24-pin dot matrix, Canon inkjet and Laserjet printers. The serial port claims 9600 bps, but I can only make my NC100 work reliably at the full speed using Xmodem and the AC adapter. This seems to be a common problem probably because the AC adapter supplies 10 volts and the batteries only 6.
B3.1) Printing 07/14/99
The NC can use dot matrix, inkjet and laser printers with its built-in drivers (for emulating Epson, IBM, Canon, LaserJet). The LaserJet printer driver doesn't seem to be fully implemented. It doesn't support changing font sizes (at least in the german version of the NC100). If anyone fancies writing the necessary software, we'd love to hear about it...
- B3.2) Extra Memory 09/09/2009
A battery-backed PCMCIA memory card (SRAM) will keep data even if your Notepad crashes and increases the available memory. It also allows you to create a file with BASIC bigger than 2048 bytes. This is because BASIC allocates all available memory on start-up except 2048 bytes. The memory card (maximum of 1 Mo) can be bought from :
- Primary Simulation Inc., 2963 Mozart Drive, Silver Spring, MD 20904, USA. http://www.psism.com/sramsp.htm
- - Talisman Electronics, P.O. Box 26 Pangbourne, Reading, RG8 8TL. - Telephone 01491 671914. http://www.talisman-uk.com
- Vikant Corp., 512 Kb or 1Mb cards (http://www.vikant.com or https://secure.webcom.com/vikant/onlineorder.htm
B3.3) Disks 08/15/99
Cliff Lawson (NC Project Manager): if you have an NC200 you already have a disk and built in Ranger disk routines. If you have an NC150 then the only bit of Ranger code is the terminal but it contains a hidden "hook" which allows the Ranger external disk to be connected to the machine and if you have an NC100 there is no Ranger code in it at all.
B4) How do I connect it to a PC ?
B4.1) What's the cable ?
Brief instructions are given in the manual. You can either use the LapCat parallel port system or use a standard "null modem cable", available from most computer parts shops. If you really want to make your own, the NC serial port is a 9-pin RS232, and the PC cables are:
25 pins at PC 9 pins at PC
NC PC NC PC 2 ----------- 2 2 ----------- 3 3 ----------- 3 3 ----------- 2 4 ----------- 6 4 ----------- 6 5 ----------- 7 5 ----------- 5 7 ----------- 5 7 ----------- 8 8 ----------- 4 8 ----------- 7
Use a terminal program on the PC (Telix supports XModem file transfers as well, but standard windows terminal/hyperterminal works ok for text). Set both ends to the same speed (9600 is fine), 8 data bits, no parity, 1 stop bit, RTS/CTS handshaking on and experiments until it works...
B4.3) Converting Word Processor Files 04/29/2000
Converter programs are available for both PC and NC to convert from the NC's protext to RTF on the PC :
- for msdos : ftp://ftp.lip6.fr/pub/amstrad/nc100/nc2rtf.zip - for NC : ftp://ftp.lip6.fr/pub/amstrad/nc100/nc2rtfb.zip
B4.4) How do I connect it to a BBC micro 08/15/99
You will need a 5 pin C-type DIN plug, a 9 pin serial plug, some cable, and the instructions from http://www.gre.ac.uk/~st702/qanda.htm#q11
Oddly enough, the Notepad includes a copy of BBC BASIC. This allows you to create your own programs and download other peoples. However, some people have found that using the WP to look at a BASIC file can crash the machine, so backup your important files first.
B5.1) Where can I find programs for it ?
- ftp.maekong.york.ac.uk/pub/BBC - http://www.ncus.org.uk Tim's Amstrad NC Users Site, go to links
B5.2) Can I use the Word Processor to enter listings ?
Certainly, to go from WP to BASIC type "*EXEC filename" into BASIC (don't forget line numbers). To go from BASIC to WP, load the program and then type:
*SPOOL document LIST *SPOOL
Don't put formatting (bold, etc...) in the program.
B5.3) Can I make a program auto-run ?
Of course, just save it with the name AUTO and whenever you start BASIC, it'll run.
B6) Other Programs 07/11/99
ZCN is a free operating system for the NC100. It's largely compatible with CP/M 2.2. It runs most CP/M 2.2 programs, including ZDE, QTERM, Mallard Basic, and Hitech C. It can also run the NC100's ROM BBC Basic as if it were a native ZCN program. You need an NC100 and at least one PCMCIA memory card to use it, a separate computer (perhaps a PC) and a serial lead to get the system code to it for the first time. It's available from ftp://ftp.lip6.fr/pub/amstrad/nc100 or http://www.ncus.org.uk
B7) I've just crashed it...
If you're lucky, switching it to standby and back will get you out. If you've got context saving on then it definitely won't. Try these: switching on while holding Function; switching on while holding Function, Stop, Del and the right-hand Shift; removing all the batteries (including the lithium cell) and the power adapter and trying to switch on. The last two definitely blank the memory. The first two don't always, but they don't always fix it.
B8) I've just broken it...
Try CPC supplies on +44 1772 654455 (Main switchboard) or Email their fax machine at remote-printer.Sales 184.108.40.206.220.127.116.11.18.104.22.168.tpc.int and ask them to 'phone you! Failing that, call Amstrad (see A2.2
B9) Help! Where to ask 08/15/99
Since the demise of Amstrad and Tandy stopping to sell the Notepad, the best place to ask for help is the newsgroup comp.sys.amstrad.8bit Free user support on Protext, the NC series word processor, from Brian Watson (protext spheroid.demon.co.uk).

C - Amstrad PCW
C0) PCW presentation 08/04/2001
Amstrad made the following PCW systems :
1) PCW8256 2) PCW8512 3) PCW9512 4) PcW9512+ 5) PcW9256
- 6) PcW10, see http://www.fvempel.nl/pcw10.html
1) had 180K drives, 2) had a 180 kb A drive and a 720 kb B drive, 3) had only 720 kb drives. All subsequent models had 3.5" disks using CP/M format at 720 Kb until 7) when it switched to 1.44 mb in MS-DOS format. The PcW's (no capital 'c') all used EMT rather than EMS early morning start files with 3.5" drives. The PcW 9512+ was a look-alike from the older 9512, including the daisy-wheel printer. The 9256 (256 kb memory) was a redesign of the 8000 series, with thesame dot matrix printer and keyboard, but in a more modern lookingdesign. The PcW 10 resembled the 9256 but had 512 Ko.
The PcW16 is a radical digression who's sole "raison d'être" was to make a true WYSIWYG product but this meant a change in the screen and processor (to 16MHz) which meant that it could not be kept compatible with the previous models (though documents ARE compatible).
C1) Emulators and utilities
C1.1.1) Joyce 06/09/2004
A superior PCW emulator with loads of features. Currently at version 2.02 (stable) or 2.1.5 (unstable). The 2.1.1 emulates the PcW 16 as well, version 2.02 all the other PCW and PcW models.
JOYCE 2.x is an integrated program: most utilities for e.g. converting disks to images (including MicroDesign disks) or vice versa, can be accessed through the menus. Features include, but are not limited to:
- emulation of all PCW's (as from 2.1.1) with additional memory and hardware. - emulation of additional hardware includes amongst others: mouse, serial/ parallel port and 2mb of memory; - support of actual disc drives; - virtual hard disc drives (8 mb each); - DOS directories for reading or writing, export and import tools; - one disc image included, with loads of CP/M tools, for use with JOYCE; - a variety of settings, including the original color settings of the PCW screens; - printer support. Either through LPT ports or rerouted to file (e.g. superb matrix printer emulation in Adobe PDF files); - the Windows version allows for easy creation of print screens (very useful for an editor);
Check the documentation for obtaining or creating the boot disks.
Available on http://www.seasip.demon.co.uk/Unix/Joyce/
The (older) version for DOS v 1.36 is also still available.
C1.1.2) Joyce MAC 11/08/2004
MACOs port of Joyce by Richard Bannister at http://www.bannister.org/software/emu.htm
C1.1.3) M.E.S.S. 06/09/2004
You need the boot images. M.E.S.S. should not emulate other hardware than the standard (i.e. no Centronics parallel port on a PcW 9256).
C1.2) Utilities 08/04/2001

C3) Transferring between PCW and PC 08/08/2004
Transferring data from floppy discs is easy if you have a 3.5" drive: all PcW's have one. A PCW (the 8256, 8512 and 9512) can be provided with such a drive. The free software CPM.EXE from Ansible Index at http://ai.ansible.co.uk/ can read CF2DD (double sided discs for drive B). If you have a 3.5" disc, reading it in a PC will be easy. If you only have a 3" drive you could opt for mounting the B drive in your PC (see C3.4). If you have other logical disc formats on 3.5", Sydex 22DISK will give you the best results.
Summarising the hardware conversion alternatives:
- 3.5" drive on PCW (DIY possible), - LocoLink between PCW and PC, - RS 232 serial null-modem between PCW and PC (DIY possible), - 3" drive on PC (DIY possible), - acoustic communication (DIY possible).
The 22DISK, MS Odball, PCWTrans and CPM.EXE software is freely available: 22DISK still is shareware formally and should be purchased (USD 25, an unsupported license) with Sydex. Of these programs 22DISK is the only one that can handle all disc formats for the PCW : some formats require additional definitions, some common ones listed in
If you have discs that have been formatted by DISCTOOL (the one from Matthijs Vermeulen, not the Moonstone program with the same name) which offered variable combinations of directory- and data-
- allocation, see the site http://www.fvempel.nl/.
There are quite a lot of commercial alternatives around: among others Moonstone 2-in-1 and DDriverPCW (a DOS driver that allows disks to be read and written on a PC). These two can still be obtained from LocoScript Software.
Besides the hardware process you will need to pay some attention to the file format as well: at least where LocoScript is concerned.
The simple and cheap option is to export the documents on the PCW to ASCII (American Standard Code for Information Interchange - the "language" that works with most computers, except for Windows which uses a slightly different dialect called ANSI). By exporting to ASCII your files will be restricted to the default 256 characters available with ASCII (quite a downgrade from the 600 as offered by LocoScript) and you will lose formatting, headers, footers, page numbers and accents. When you opt for the PAGE IMAGE attribute, present on all versions of LocoScript, you will at least retain some details like tab stops (replaced by spaces) and margins, but you definitely will have to check the end-result on the PC. When combined with mounting a 3" drive on a PC or (more expensive) a 3.5" drive on a PCW it is a cheap DIY solution, useful and reliable for confidential data or data that you do not want to risk losing in the mail.
If you want to retain the document settings, layout, accents and the like you will have to convert the document(s), using the available commercial programs:
- Ansible AILINK - LocoScript Professional or LocoScript Easy with or without LocoLink (for Windows)
Which one suits you best depends on your budget and purpose. The AILINK http://ai.ansible.co.uk/ can read CF2DD format disks and convert all LocoScript formats (from 1 to 4) into a.o. Richmond Text Format, a format commonly used in word processors. At GBP 19.50 it may sound expensive and I have not used all of it's features but it seems like a good alternative to reformatting documents or buying a DOS word processor for conversion only. AILINK is a true Windows program (allowed for the occasional DOS box) and offers amongst others RTF, RTF for Word, WordPerfect 4.2, ASCII, ANSI, HTML and some other formats.It allows for mass copying and converting and seems to produce a 1:1 copy including formatting and accents. Do note that AILINK can read from CF2DD only (no CF2 or other formats) and does not solve the 3" problem, unless you mount a 3" drive in your PC.
The LocoScript alternatives are more expensive but they also provide the hardware solution (LocoLink, part of LocoScript, does). Data conversion retaining layout and accents is also seamless but there is no mass-tagging option and the PCW LocoScript source file has to be translated to PC LocoScript source file before it can be exported to other formats. But then again, the LocoScript PC word processing software is not bad either. LocoFile datafiles need to be "squashed" by LocoScript Professional or PC Easy before they can be used. Conversion requirements do not apply for LocoLink for Windows, only the earlier version requires it.
To use the data from a LocoFile datafile with other PC software you will need to use LocoScript Professional or LocoScript PC Easy Mailmerge commands to output the data to a LocoScript document. You should then export the document as above. Or LocoLink for Windows can be used to convert datafiles to DBase or FoxPro formats.
I have heard from other projects on the subject, but have not seen products so far.
Using Mallard BASIC programs on the PC is possible, though the following aspects should be considered. First of all, Mallard BASIC has a special file format that (I think) can be read by the PC version of Mallard BASIC only (an expensive and therefore rare item: I do believe it is still for sale, though). Saving it into ASCII format is easy though: just add the attribute A when you (re-)save a program, e.g. SAVE "PROG.BAS",A will save the file in ASCII format. This format can be read by 99% of the other Basic dialects. Also, unprotect your file program, if it has been protected, before exporting it.
Although Mallard BASIC is pretty much standard in command convention, there are a couple of exceptions. 1) JetSam keyed-index databases cannot be used by other Basic dialects: redesign of the program to a sequential or random access database structure will be required. 2) GSX, the Graphics System eXtension, does not have an MS Dos equivalent. In fact it is not part of BASIC but if your application uses this add-on on the PCW, it can obstruct the proper working on another Basic language. It will have to be replaced by graphics functionality offered by the other Basic. 3) Machine code and peeks & pokes will not work at all. If the program contains too much of these: forget it... 4) The different hardware can be a bit of a problem when the program uses the PCW hardware to it's maximum. The big screen and the Epson FX-80 emulation on the printer may force you to re-write the program.
I found that good old GWBasic, supplied in numerous quantities with MS Dos, works best when porting PCW Basic source to other computers. Check a program up-front for the mentioned issues and decide whether it is worth your while to adopt it on a PC, to redesign it on a PC or to use a PCW emulator on the PC. Do be careful when modifying a PCW Mallard BASIC program on the PC, though!
Using PC data on a PCW is also possible: ASCII would be the normal standard here but several Dos and Windows programs offer export formats for older software (e.g. dBaseII, SuperCalc II) too. LocoScript Professional or LocoScript Easy documents can be read by LocoScript 2.50 or later on the PCW if they have been saved in the LocoScript 2/3 format, a feature offered by LocoScript Professional 2 or LocoScript PC Easy (version 1.01 or later).
LocoFile databases from a PC need to be extracted to a LocoScript document and can be converted to the PCW. On the PCW the LocoFile database needs to be rebuild.
Software Versions and Requirements (Howard Fisher)
To use LocoLink, LocoScript Professional or LocoScript PC Easy is required. The above information applies to versions since 1 st January 94 - LocoLink for LocoScript Professional, Version 1.08 or later of LocoScript Professional and Version 1.01 or later of LocoScript PC Easy. To export from LocoScript on the PC to the PCW you need v2.50 or later of LocoScript on the PCW. LocoLink for Windows can convert documents and datafiles produced with any version of LocoScript.
Alternatively, you can use a disc transfer service both to copy the discs and if necessary convert the files to other PC word processor formats.
Here are those which can transfer and/or convert files :
C3.1) 3.5" drive to a PCW 06/09/2004 (this section by Axel_Berger Su2.Maus.De)
Amstrad uses a 26-pin floppy bus, which is exactly similar to the 34 pin Shugart bus but with 4 signals, that are never used anyway, left out. In both cases all odd numbered lines are grounded and all signals are active low. The unused lines of the Shugart are: (usage of some of them varies, I have tried to state the most common one)
2: Density 4: Head Load 6: Drive Select 3, Ready 14: Drive Select 2
So you have to splice the cable and fit it to a 34-pin connector as:
Amstrad Shugart Use 2 8 Index 4 10 Drive Select 0 6 12 Drive Select 1 8 16 Motor On 10 18 Step Direction 12 20 Step 14 22 Write Data 16 24 Write Gate 18 26 Track 00 20 28 Write Protect 22 30 Read Data 24 32 Side Select 26 34 Ready
There is one problem with the choice of drive: The PCW expects to get a "Ready" on pin 26 and IBM compatible 3.5" HD don't deliver it. Drives used to have jumpers but with the Gates monopoly they don't have them anymore, so you might have to improvise something. A direct connection from Drive Select to Ready by Diode will deliver the signal too soon, reading will work, as the computer gives it a second try but writing will be dangerous. I haven't needed to try that, I have got enough old 720 k drives that can be jumpered or otherwise adapted to fit.
Some people have experimented successfully with a diode protected push
switch with a signal from motor on. See http://www.king27.freeserve.co.uk/
*BEWARE OF A SERIOUS PITFALL* Amstrad has the *power connecter wired the other way round* and on top of that uses yellow for 5 V and red for 12 V!!!! Note from FvE: this remark is not valid for the PCW 9512!
Details and a photo-session on the subject can be viewed on :
I have added a changeover switch that allows me to make the 3.5" either drive A or drive B and the original 3" one the other. Of course my 3.5" disks have to be formatted differently for either use and the 3" accessed as drive B will not work, but allows me to boot from 3.5" and then switch over to use the full 720 k capacity.
C3.2) LocoLink (for Windows) 06/09/2004
LocoLink is a cable that can connect a PCW to a PC with a parallel cable (connects to the expansion port of the PCW). The software is a part of LocoScript Professional or LocoScript PC Easy and converts the complicated format of the PCW LocoScript file seamless.
At present there are two versions around, the old LocoLink and LocoLink for Windows. The latter one provides mouse support and a wider range of direct conversions to PC format WPs.
A Laplink serial cable can also be used.
C3.3) RS 232 08/04/2001
RS232 can serve for a null-modem cable to connect to a PC. In order to create such a cable (when you buy one in a store, do check for the prescribed connections!) connect the pins as stated below.
PCW PC 2 3 3 2 5 20 7 7 20 5
Pins 4, 6 and 8 must be connected to each other on the same side! It may look like a classic 'short circuit', but it has to be done ! So : 4, 6 and 8 connected to each other on the PCW side and 4, 6 and 8 connected on the PC side connected to each other.
A Laplink serial cable can also be used.
For software I would recommend Kermit. An old (v 3.0, 1990) but functional DOS version can be downloaded :
If you cannot convert it to a 3" contact me. A safe speed is 9600 bps if you have a standard interface. Other transfer products like CSTAM and Pipeline will do too. If you have a high speed model you may try a higher baud rate.
C3.4) 3" Drive on PC 08/04/2001
Operating a 3" 720Kb drive on a PC is very well possible: the cable required is already presented under A3.1 (the CPC resembles the PCW in this respect). However, in view of my experiences with it I would recommend it only to experienced Do-It-Yourselfers. I would not take the risk and go through the trouble for just 10 3" disks. Besides the hardware troubles you probably still face the problem of how to convert LocoScript to a format common on PC's. If you absolutely want to do it,
- consult http://www.fvempel.nl/3pc.html (specific details
for the PCW and a photo session).
Getting the data on a PC is a problem only with a 3" drive as mounted in an 8256, 8512 or 9512. When you have a 3.5" fitted there are plenty of utilities around to read from CF2DD format (Ansible's free downloadable CPM.EXE, the shareware program 22DISK from Sydex or the PCWTrans/MS Odball programs by John Elliott). The next problem is getting the data into a format that can be used on a PC: most programs (dBase, SuperCalc, Masterfile, TasWord, WordStar, MicroDesign) have a version commonly available for MS Dos and the CP/M file can therefore be imported in the PC counterpart easily and without loss of details.
C3.5) Acoustic communication 08/08/2000
At present experiments with acoustic communications are being conducted (in Spain). This would allow for cheap one-way communication (only the PCW to PC) that requires a PCW 8000 model, a PC with a sound card and a microphone. A short BASIC listing (that, will be made available after release of the programs) can be typed in on the PCW and will allow files to be converted into beeps (call it morse) that can be received by the microphone and converted back into files again on the PC.
The software works already: the speed (at present 25 bps) is not very fast but it is a very promising project that finally could provide 3" PCW'ers with a cheap and easy way to exchange small data files. The object is to produce a program protocol that can reliably send and receive up to 400bps with the additional + feature to record it on tape, thus allowing for playback. Subject to be continued.

C5.1) Printer 08/04/2001
The original PCW printers can't be used on another computer, being controlled by the PCW itself.
The 9 pin matrix printers, as supplied with the PCW 8256, PCW 8512, PcW 9256 and PcW 10 are basically the same. They are not fully compatible, though. Printers for the:
8256 can be used with the 8512 too. Separate data (flat) cable and power cord; 8512 can be used with the 8256 too. Separate data (flat) cable and power cord; 9256 only for the 9256. Integrated data and power cable, IBM/Centronics connector which is NOT Centronics compatible!!! 10 only for the 10. Connector type of the 8256/8512 but integrated data and power supply.
All of these printers are basically identical, support 7 bit Epson FX-80 and use Seikosha SP 800/SP 1000 ribbons (available in both nylon and carbon).
The matrix printer is one of the first parts that will wear and eventually break down (after 10 or more years). Spares cannot be obtained and repair is often an expensive and insufficient option. I can supply used print heads (at postal expenses) but no guarantee towards quality or life span. In view of the price of a new computer plus printer, expanding a PCW with a Centronics printer interface might be a realistic alternative.
You would need to pay attention to the availability of printer drivers for LocoScript and CP/M and/or the emulation modes offered by the new printer. The original PCW printer is Epson FX compatible: partly (7 bits only). Other common emulations used on PCW's are HP Laserjet III, Diablo 630 and Canon BJ.
The daisy wheel printer as supplied with the PCW 9512 and PcW 9512+ are compatible with each other only. The part that can break down first in this printer is the hammer, which is subject to violet action. Spares can be obtained and replacing it is easy. The standard ribbon type is Olympia Carrera II.
Some of the 9000 models were supplied with standard non-Amstrad printers as well, a common model was a Canon but Epsons were supplied too. Being standard models of printers, they are beyond the scope of this document.
The PCW 9512, PcW 9512+, PcW 10 and PcW 16 have a standard parallel Centronics printer interface, the other types can be equipped with such a port through the expansion port (by means of an add-on
interface). Several models were made some of them featuring additional options like a serial RS 232 port, a real-time clock, or additional memory (up to 2mb). There is a lot of software for the PCW's that can make use of external printer: LocoScript (using softfonts - downloaded from the RAM disc) and MicroDesign (up to 400 dpi graphics) are the top in this respect. But utilities like landscape printing and screen dumping in text or graphics mode for CP/M are around too. Again, before considering attaching an external printer to the PCW, attention should be paid to the best combination(s) available!
C5.2) Keyboard 08/08/2000
Three different keyboard layouts were produced for most PCW's: the QWERTY lay-out used for the majority, the QWERTZ for Germans (Schneider's) and AZERTY for French machines.
Usually reliable sources have told me that the entire series of PCW keyboards (8256, 8512, 9512, 9256, 9512+ and 10, that is) can be exchanged. I have not tested them all but found that the Teqniche (an XT keyboard meant for the 8000 series) does indeed work with a 9000 model, so the statement should be true. In how far all keys will respond depends on the software version used but I see not much reason to exchange keyboards, unless you want to use the 9512/9512+/Teqniche keyboards on the other machines. PCW keyboard do not work on other computers (or the other way around).
Interesting detail is that the PCW keyboards (already customised to work as a dedicated word processor) can be altered entirely to match the user preferences. Besides the standard CP/M SETKEYS.COM there is a more user friendly SMARTKEYS (a Resident System Extension, RSX) and LocoScript has the LocoKey program available to do the job.
A negative side effect of the customised keyboard is the confusion when confronted with standard key-notation of PC (or CPC's for that matter). Here are some useful keys to remember in CP/M:
PCW: Other computers: EXIT ESC ALT CTRL SHIFT+EXTRA+EXIT CTRL+ALT+DEL You will find the three keystrokes above useful when reading computer books or magazines: they confirm to the standards in the computer industry. ALT+P will for instance function as a toggle to turn print output (next to screen output) on or off. EXIT will work for certain strokes: it is the ESCape character that allows control over the hardware. This is usually from software to e.g. set the printer to italic. You can input some of these ESCape codes through the keyboard: EXIT+E+EXIT+H+ENTER will clear the screen. CP/M 3.0 converts all input to capital letters unfortunately so all small letter ESC's will not work: consult a good book on the subject. Some special key stokes on the PCW: PTR Printer control status EXTRA+PTR graphics screen dump of the screen on the printer ALT+ENTER CAPS lock (like SHIFT lock, except for the numeric keys) ALT+RELAY NUM lock (enables the 'numeric path', the section were the cursor keys are located to produce numbers.
Using the standard Amstrad SETKEYS (or the enhanced SMARTKEYS) will allow you to redefine practically all keys on the board as long as you know it's number and the number of the character or ESC sequence you want to produce. Certain keys can take more than one character: the so-called expansion keys. There is a shorter way to modify the keyboard: the language. Take a look at the manual for the different accents that will produce.
The PcW 16 Anne (section D) has a PS/2 compatible keyboard and will NOT work on a Joyce!
C5.3) Disc drive 08/08/2000
The 3" disc drives of the 8256, 8512 and 9512 can suffer from the some problems as the Amstrad CPC can. Refer to section A5.1) for tips on how to solve these. The usual problem with a PCW 3" drive is a worn or broken drive belt. The typical symptoms are: unable to boot, LED burning constantly, slipping motor noise and a variety of disc and/or data errors. When you have only one boot disk but do have more 3" data disks, try to boot from a data disk. If the PCW does not respond with three beeps (no system disk in the drive) chances are that the belt is defective.
C6) Additional hardware 08/08/2000
C6.1) Memory up to 512 kb 06/09/2004
All PCW (except the 16) can take a maximum of 512kb on the main board and all of them do have this amount of RAM, except for the PCW 8256 and PcW 9256, which came with a standard of 256kb. These machines can easily be upgraded to 512kb using 8 x IC 41256 in the range of 100-150 nanoseconds. This is a standard chip, old fashioned nowadays and should cost a maximum of 10 euros.
All extra memory goes into the RAM disc M and will not attribute to the computers internal memory capacity of 64kb. CP/M and LocoScript use a so-called bank switching system that allows the use of more than 64kb: the remainder of memory will go into drive M. A PCW with 256kb has 110kb drive M, a 512kb model has 368kb drive M. Increasing M can be very useful, as e.g. disc copying is done through the RAM disc. A 368 RAM disc will allow you to copy a 720kb disc is 2 passes (4 disc swaps). Moreover: several programs can work with virtual memory (see below) and starting (and running data-intensive) programs from disc M is a lot faster than from floppy disc.
C6.2) Memory beyond 512kb 08/08/2000
Besides the maximum of 512kb on board PCW's can use memory above that:
the same applies as with normal RAM memory above the bank switching system. It will be assigned to the RAM disc M. Again, this is very useful: besides DiscKit, programs like LocoScript 3/4 (softfonts), MicroDesign (high resolution up to 400dpi), The Rocket, Scratchpad Plus (the latter two spreadsheets), Flipper (multitasking), The Network (networking) and several others can use disc M as virtual memory, thus allowing for more features or capacity.
Several interfaces (see C6.3) were put on the market, while Cirtech also produced an on-board version called the Sprinter. That card replaced the Z80 processor by a faster processor on 8mHz and expanded memory up to a maximum of (I believe) 2 megabytes. Besides the processor you had to remove a memory chip as well in order to plug the Sprinter card onto the main board of the PCW. It fitted for the 8000 models only, as the sizes of the main boards do vary.
C6.3) Interfaces (various purposes) 08/04/2001
An interface is an add-on that fits on the expansion port on the back of the PCW and provides additional communication ports or memory (at least that is how I define it). An interface is therefore always an add-on, but not the other way around. A break-through connector is a feature that allows a second add-on to be connected on the break- through connector (basically a second expansion port). This 'back-packing' of add-ons is commonly known as the Christmas Tree and can lead to potential dangerous situations regarding the power supply of the PCW or the risk of losing an add-on. The later is fatal to the life of any PCW when connected: never (dis-)connect devices while the PCW is switched ON!!! Many of the add-ons are no longer for sale.
- Amstrad/Schneider (the German model known as CPS - Centronics Parallel Schnitstelle). Offered a Centronics parallel and RS 232C serial port but does not feature a through connector and has a female Centronics connector: with the normal type of printer that requires a cable with Centronics male/Centronics male connectors, rather than the stand Centronics male/IBM. - SCA Professional & Professional Plus. A look-alike from the original CPS, but the Professional Plus has a battery-backed up clock plus software. - Cirtech parallel interface. Low-budget printer interface with only a Centronics port. The right, market-standard, connector though! - Cirtech SpeedPrint. Print spooler that frees the PCW of print jobs. - Cirtech FlashDrive: non volatile RAM disc memory (data remains after switching off the PCW) in two different sizes of 1 Mb and 2Mb, with and without through connector
- The SCA Rampack is an add-on of additional RAM memory of (I believe) up to a maximum of 2mb. Break through connector for a second add-on. - LocoMotive RAMpack, additional memory. Marketed when LocoScript started featuring downloadle soft fonts (with version 3).
- Phono Set (Vortex) offered an RS232 port and an acoustic modem. Sure wish a had such a beast, considering the Spanish project for acoustic comm's.
C6.4) ProScan 08/04/2001
A hand-held scanner, 400dpi, by Creative Technology for use principally with MicroDesign and some other graphics packages. Uses an add-on box for the expansion port (through connector available). "Best in the West".
C6.5) MasterScan 08/08/2000
A scanner that is fitted on the print head of the 9-pin dot matrix and connects to the expansion port (break through available). Sheets that are fed through the printer can be scanned and digitised.
Although the format supported was screen size only, the supplied MasterPaint (a Mac look-alike) is a piece of art in itself.
C6.6) Electric Studio Light Pen 08/08/2000
Light Pen from Electric Studio (PCW variant of the CPC device) for use with, among others, Fleet Street Editor. Break-through available.
C6.7) Electric Studio Digitiser 08/08/2000
Video digitiser, also from Electric Studio. European PAL system, works neat, although the monochrome effects of saved snapshots sometimes need editing. Break-through connector is available.
C6.8) Robotics Hegatron Grafpad II 08/08/2000
Graphics drawing pallet with a substitute keyboard (using the pen). This package was often used for (electrical) technical drawing.
C6.9) Intergem interface 08/08/2000
A lame duck: an interface that allows you to connect an 80 track disc drive from a BBC computer to the PCW. Not very useful, considering the number of BBC owners that would want to offer their drive(s) for this purpose.
C6.10) Disc drives 08/04/2001
Several manufacturers made (Pace) and still make (Pinboard) disc drives packages that allow 5.25" or 3.5" disc-drives to be connected to a PCW. In view of the relatively minor adjustments that are required for a do-it-yourself operation not very useful, unless you consider an external power supply (power supply is the PCW's weak spot). And with the exception of the Pinboard drives that are supplied in a variety of models. Besides switchable types that allow a 3" 720kb to be operated next to a 3.5" 720kb (both as drive B) there are also "double deckers" and versions that allow an 8000 model to boot from 3.5" 720kb discs.
Pinboard is still in business : Pinboardcomputers btinternet.com http://www.btinternet.com/~pinboardcomputers/
LocoScript software supplies a 3.5" that fits into the bay of a 3" drive, email sales locomotive.com
ACW Soft (Germany) offered a kit to connect a 3" to the PC, Eureka 01329 239953 (UK) still does.
C6.11) Hard disks 08/08/2000
Several hard discs were made too for the PCW series. - The ACC Computer Services came as a 10mb hard disc, with Tasword (LocoScript was not supported). - Vortex (Germany) offered the WD2000 of 20mb. - WEB made a 20mb hard disc. - ASD supplied one in 10/20/40mb capacity with some utilities. - Cirtech offers a variety of hard discs with patched versions of LocoScript 2. Others were made for networking purposes and are very rare, considering the expensive software (back then) which came with these.
C6.12) Margin Maker 08/08/2000
A small, inexpensive add-on for the 9-pins matrix printer that allows for a shortcoming in the PCW's printer. The PCW printer does have a ruler but lacks a device that will align paper to the chosen left of right margins.
C6.13) Mice & other input devices 08/04/2001
Lots were made for the PCW series: the Kempston 2-button and the AMX 3-button mice are the most familiar but Star, Electric Studio and Gerdes also marketed these. Most DTP packages support these. The AMX features a through connector.
Cirtech produced the keymouse, which unlike the others worked through the keyboard socket.
d'k Tronics produced a joystick for the PCW and several adapters appeared from various producers. Some were supported by PCW software, others were not. A simple diy scheme was around that allowed a joystick to be connected to the cursor keys of the keyboard. Also see the sections on the light pen C6.6) and the graphics tablet C6.8).
The PcW 16 (see section D) has a PS/2 mouse.
C6.14) Teqniche keyboard 08/08/2000
A standard 102 keyboard (IBM AT type) was made for the Amstrad PCW series. It fits on all PCW's except the PcW 16 (which uses a PS/2 type). A real heavy keyboard featuring separate [F.] function keys, cursor and numeric keys, adopted for the Amstrad word processing layout.
C6.15) LocoLink & LocoLink for Windows 08/08/2000
C6.16) d'k Tronics sound synthesiser. 08/08/2000
A sound synthesiser was produced by d'k Tronics but I do not know of any details. Some DIY layouts were published in magazines to produce sound add-ons for PCW's.
C6.17) ISA card. 08/04/2001
The layout to make an Industry Standard Adapter for the PCW is available on http://user.tninet.se/~psr810p/
C6.18) Various DIY layouts. 08/04/2001
A number of layouts for diy expansions to the PCW can be found on:
Amongst others they contain serial and parallel interfaces plus some applications for these and small modifications to the system.
C7) Fanzines 06/09/2004
No magazines are now produced, the last two PCWPlus and Amstrad PCW User ceased production in 1998 though the information they contained is still valid. Two Fanzines exist The Disc Dive produced by The British Amstrad Group, see above for details of membership or receive copies. The other is PCWtoday, though issue has become intermittent of late. Their web site http://www.pcwtoday.co.uk gives details and subscription rates.
Joyce Bulletin, in Dutch, is the quarterly magazine of the Joyce Computer Club Amsterdam. It often includes 3" Disks. It is now available as on-line (Dutch only) Adobe PDF file on: http://http://www.amstradcg.nl/. It deviates slightly from the paper version, due to mismatches between the page layout in PDF and printer settings.
D) PcW 16
D0) PcW 16 presentation
This presentation comes from a csa8 article by Cliff Lawson.
Unlike all previous 4MHz Amstrad Z80 machines this has a 16MHz Z80 core (hence the 16 in PcW16). I know a lot of people "hate" us for not making it binary compatible with the previous PCWs but the fact is that we couldn't do it and design the architecture optimised for graphic word processing software (which means that it is optimised for BitBlt type graphics). The screen is actually kind of VGA compatible in that it is 640x480x2 with a straight raster mapping rather than the character scan raster map and roller RAM of previous PCW (in fact a lot like the 640x200 mode on the CPC I suppose).
The main thing that makes this machine such a dream to develop for is the graphic OS (windows, icons, mice are all in there in the core OS). The OS was developed in the main by Simon Hargreaves of Creative who is renowned for MicroDesign on the previous PCWs.
The Rosanne operating system that he has put together is just so advanced compared to the other Z80 operating systems that we have been responsible for in the past that it just seems a shame that any Z80 development talent out there isn't considering writing stuff for the system - you'd enjoy it, believe me.
Apart from the graphic stuff, message based event system (a la Windows) you've got window, menu, dialog, scroll bar, radio button, checkbox, etc. etc. all immediately available in the OS.
The OS also has a rich set of disk/flash disk filing stuff. The system read/writes MS-DOS format files/disks and can also read (not write) CP/M format files/disks.
It has fairly advanced memory alloc/dealloc routines and OS support for 24 bit banked addressing.
There's an RTC in there so functions exist for that.
Even the spell checker in the WP is exposed as an OS callable function.
Perhaps best of all is the huge support for variable typefaces for output to both the screen and printer using Swiss and Times in 6, 8, 10, 11, 12, 14, 18, 24, 36, 72 point.
The machine has an unused RS232 on the back so there's a possibility for developing email/news software - perhaps even a web browser!
There's a help engine in the OS so adding Help support to your apps is also very easy.
For doing maths there's a 5 byte floating point system in the OS so sin/cos/tan/log/exp are all provided.
If you want to read more about this operating system then get: ftp://ftp.lip6.fr/pub/amstrad/misc/ROSANDOC.ZIP or email me direct and chat about it.
