Title: Who wants IDE drives on the PCW?
Post by: JonB on 13:43, 22 January 17
Hi


Now I have the PCW IDE driver working with my prototype hardware, I am looking to get some boards designed and fabricated. Who's interested in buying one (or more)? There are several options:
There are some design options, too:
Before I expend huge amounts of effort on this, I'd like to get an idea of who will be interested and what the preferred design option is. The objective is to produce something cheap - don't expect it to cost more than (say) £30 all in.

Quick demo: https://youtu.be/fNb4eoOV6Ik (https://youtu.be/fNb4eoOV6Ik) - should be viewable at 1:00pm UK time 22/01/2017 (currently uploading it).

Please reply below.


Cheers
JonB

This is CPM IDE driver, wow! Wouldn't it be possible to get this driver working on a CPC with a IDE connected?
Title: Re: Who wants IDE drives on the PCW?
Post by: JonB on 16:50, 22 January 17
Yes, possible, but this is PCW only for now. The CPC is next. It uses a different method to address I/O devices and its expansion port is different to the PCW's, so a different adapter might be needed.

Understand. I don't own a PCW but working with CP/M together with a hardrive would be a dream. Sadly I have no clue about writing a driver for CP/M.  :(

This'd be something I'd really be interested in.  Ideally I'd like two of them for both my 8256 and 9512.  In terms of board layout, I'd be much more keen on the third one with the shim card attaching to the Z80 socket.  Just personal preference although anything that would allow me to continue using my other add-ons that I've got would be good.  Not too fussed over how the boards are done, although again my preference would be for them to be made in a single batch and then I'd just but the components and fit them myself.  Do enjoy my soldering so it'd be another pleasent diversion for me.  Also, getting all the boards made as a batch would potentially bring the price down per indivdidual board depending on how many were manufactured.

Jon,


Yes please, I'd be interested.


However, I'd MUCH prefer the edge connector to plug onto the extrusion (assuming that it could also plug onto the extrusion carried thru the SIO box).


This would be more helpful, as I would not be using the unit all the time.




I generally have the SIO connected, as this has a clock/battery chip in which I find some use.


More important, I'm happily using my PCW with the 5.25" A: and 3.5" B:.   I need to use CP/M 1.1 for this, and 1.1 seems to be the only system that has allowed a 'patch' to keep the 5.25" A: working OK with both formats that I use (SS and DS).   But of course, to use your system I will need a later version, like say the 2.9 which I do have so I can use the FID.


Anyway, the edge connector option seems pref for me.   But I might be persuaded.


No idea if my Z80 is on a socket or not.   Next time I'm inside, I'll look.

What? CP/M 1.1 on a PCW?  :o


You know my driver is FID based. It will not work with CP/M 1.1 although I do know how to build it for 2.2.
Title: Re: Who wants IDE drives on the PCW?
Post by: GeoffB17 on 19:18, 22 January 17
OK.


All my earlier references to 'CP/M xxx' please read 'CP/M+ xxx' as per the version ## that appears on screen when you boot.   I note that on your new video you're using 2.12, however I have 2.9 which also copes with FIDs.


;-)


Oh, just to complete the rest of the original question, I'd be fine if I could get a board made, then I'd just get rest of bits and make it up.   Soldering not too bad.

Ah you meant the Amstrad version.. yes, no reason why it won't work for you, as long as it supports FIDs.

Now is the time to look at what changes are required to make it CPC compatible, before you start producing anything. With clever layout or even multiple population you could make it a PCW/CPC device.

Isn't it just using A8-A15 for the I/O address lines, and a different IN/OUT instruction? But the CPC's expansion port is different, too.. and it would either need a patch area for that, or at least 3 extra chips. I don't want to use any programmable logic here.
Title: Re: Who wants IDE drives on the PCW?
Post by: Bryce on 10:16, 23 January 17
I haven't looked at the schematics, so I can't say, but maybe it would be possible with just an adapter connector in the middle and some jumpers. With multiple population I meant that the position for the alternative ICs would be on the PCB, but you only populate the ICs needed for the system you intend using it on.

Bigger PCB = higher cost.


But I'm getting ahead of myself! I first need to familiarise myself with some PCB design software.

Incidentally, it seems to work with Locoscript:

Could you tell all as to what the board is that holds the DOM ?
Is it the same as the model 4P that Gazza and i were working with ??


Thanks   Ray
Title: Re: Who wants IDE drives on the PCW?
Post by: JonB on 11:16, 23 January 17
My prototype uses a TRS-80 Model 4 IDE adapter that VCF users Hans01 & Gazza developed from the old schematic on the LoTech site, which itself is a derivative of a design attributed to Larry Campanell / Andrew Quinn. My design is also a derivative with slightly different CE logic. After all, there are only so many ways to connect a device to a bus! But it is different to the commercial LoTech TRS-80 card, because it doesn't have any of the line driver / buffering.

So for reference it is like Andrew Quinn's design: http://www.qsl.net/zl1wjq/trside1.htm

To connect Hans01's board to the PCW I built a 50 way IDC breakout board, then used jumper links to connect each required pin to the corresponding pin on the 50 way TRS-80 adapter box header. I do not use the EXTIOSEL line. Ther is a 50 way edge - 50 way IDC cable to connect the PCW's expansion port to the breakout card.

If you review the intro videos you can see the prototype adapter: https://www.youtube.com/channel/UCdH2u50ocnjPxPmEOyNVLsg (https://www.youtube.com/channel/UCdH2u50ocnjPxPmEOyNVLsg)

I tested it with the Rev.2 LoTech TRS-80 IDE adapter but it doesn't work properly with the PCW, so I guess we need to keep it simple.

I'll be interested in two!
Title: Re: Who wants IDE drives on the PCW?
Post by: JonB on 13:37, 23 January 17
OK MaV


Just a couple of minor concerns. First off, the PCW does not work properly with the LoTech adapter card. Secondly, having reviewed the VCF forum thread about the LoTech card and its design, I am concerned that we may have compatibility problems with some IDE devices. I recommend the PQi DOM is used (128Mb).

@JonB (http://www.cpcwiki.eu/forum/index.php?action=profile;u=901)
Just a short (and inexperienced) question regarding the CP/M IDE Driver. The IDE (PQI DOM & Controller/Decoder - as used in the X-Mass) uses 512 Bytes sector size whereas CP/M 2.2 has fix size of 128 Bytes. CP/M is able to handle 2000 tracks = 8MB?
That means that you have to partionize the hard drive into 16 Partitions / drives or less?
So, the only thing is to tell CP/M addressing via LBA and dividing the 512 Byte sector stored in the IDE Buffer by 4 clusters, and read it separately out (means change only the BIOS of CP/M)? Am I right?
Title: Re: Who wants IDE drives on the PCW?
Post by: JonB on 22:49, 23 January 17
Not quite.


Yes, it uses LBA, as a convenience so we don't need to know the disk's physical geometry. The PCW and CPC have built in sector blocking/deblocking, and the IDE device is running in 8 bit mode, too. Thus we can use all the space on the drive. Under CP/M 2.2, the driver implements the sector blocking routine itself. (This particular driver runs on the TRS-80 Model II.)


The IDE sector size is 512 bytes, incidentally, which is nice because the PCW's CP/M Plus implementation does likewise. But you must read all 512 bytes when you get a sector from the drive. Without blocking/deblocking, this would be inefficient (in terms of drive space wastage).


Although the FID interface was new to me, it does make much of the work easy. CP/M 2.2 could do with something like this. Most of the work in that driver was working out how to patch the OS and implement the rather advanced drive mapping scheme. Hard work, but fun and ultimately rewarding!
Title: Re: Who wants IDE drives on the PCW?
Post by: JonB on 19:02, 25 January 17
Now this is what we call an "untested design", because I don't have the materials to prototype it yet, and I did rather get sucked into KiCad. As it is intended to be universal, there is a set of three way jumpers to set the I/O base address of the IDE registers. The driver currently has it as C8h, but we can easily change that to something else. To get C8, you set the jumpers as 1 1 0 0 1 (A7 A6 A5 A4 A3 respectively). You can set any other base address just by resetting the jumpers, but of course, the driver must be (re)built for it.


Pwr is the power LED, and Act is the drive activity light, which flashes when the PCW is accessing the drive. I'd suggest a red LED for power and amber for activity. Or, you could mount headers here and have your lights remotely mounted (say, in the unused front panel of the PCW's spare drive).

Don't worry about the "Z80 shim connector" reference. You will have two options to plug it into a PCW:
I plan to produce both Z80 shim and PCW adapter boards, too, but for the time being you can buy shims from Zaxxon here: https://www.sellmyretro.com/offer/details/21802 (https://www.sellmyretro.com/offer/details/21802). Open up your PCW and see if the Z80 is in a socket. It is right next to the expansion edge connector, you can't miss it.

Mine is socketed, but my 9512 has it soldered directly to the board. The pin header I mentioned earlier (which you might use for an internal expansion connector) is a non standard pitch, so it will be difficult to connect a cable to it. Amstrad cheapskates..  >:(

It will be possible to connect this to the CPC machines using another expansion port adapter, but not via the Z80 shim method.

Prototype Mk 2

 [ You are not allowed to view attachments ]


This design appears to be working but I have a lot of testing to do and I need to lay out the Z80 shim and PCW expansion port PCBs. The Mk2 layout is smaller than the one I posted previously and the components are moved around a bit. It also has an additional power connector and wider tracks for +5v and GND.

SymbOS PCW support???
Title: Re: Who wants IDE drives on the PCW?
Post by: JonB on 15:10, 31 January 17
SymbOS PCW support???


You are not the first person to ask. I seem to recall trying SymbOS (when I first got my PCW) but it didn't work with my AMX mouse. The problem is I can't write a driver for it (yet) because I haven't investigated it. However.. if SymbOS already supports a hard drive then you should be able to configure uIDE to match the I/O address that its driver expects.


So: My question to you: Does SymbOS support any sort of hard drive, and if so, which one(s)?
Title: Re: Who wants IDE drives on the PCW?
Post by: RockRiver on 15:41, 31 January 17
AMX pcw mouse is the one that I have. And now SymbOS works with it.
Jörn (SymbOS coder) answered me some time ago if there are PCW users with HDD... (only few old 80's HDD pcw drives in the World)
I think John Elliott (coder of Joyce emu) has one of that.

OK, great. I PM-ed Prodatron to ask if the v3.0 SymbOS for PCW supports IDE drives. Maybe you could ask your friends? IDE drivers are easy to write if the OS interface is clean (as it is with the PCW FID). And of course, I can help.

But...


 [ You are not allowed to view attachments ]


This is the completed board layout as rendered by OSH Park. I ordered 3 of them as prototypes, £10 per board. I will assemble one and do some further testing. Also, I still have to design the Z80 shim and PCW expansion port adapter and get them fabricated. Still a long way to go, but be assured: IDE is coming to the PCW.

About now you might consider registering your interest. I need to know how many boards to order. Please also indicate whether you want the Z80 shim or expansion port adapter.


@RockRiver (http://www.cpcwiki.eu/forum/index.php?action=profile;u=264), would you mind co-ordinating on the Amstrad.ES forum for me?

Speaking of which...


 [ You are not allowed to view attachments ]


The eagle-eyed among you may notice that the host adapter on the uIDE is back to front. That's because I designed it for a left handed shim, or I was asleep at the wheel. So now I have to go back and re-route it... :(


Still, never mind - the three I ordered can be used with the shims I have here.

Here is the bus adapter board with power access and composite video output. The minimum requirement is installation of the two IDC connectors (video, power connectors and LED components are optional).

I need to fatten the power lines a bit, but that is the layout.


OSH Park costs are as follows (for three boards):

It excludes the video circuit and costs $18.80 for three boards (OSH Park again).

Hi again!

Another day, another update, and I hope this is the last one. The problem with CAD packages is you want to get everything perfect, and you keep going back and making changes, because you continuously think of ways to improve your design. So it is with uIDE, and here is version 0.4:


 [ You are not allowed to view attachments ]


The differences are:
I have also completed improvements to the other three boards. They all have fatter power traces. In addition, I conducted more testing on the prototype (in CP/M, "PIP H:=C:*.*[V]" - that's a full copy of the many files on C: to H:, both drives on the IDE device, with read verification) and there were no errors.

Board summary

uIDE Z80 Univeral IDE Adapter
Universal IDE adapter.

PCW Expansion port adapter (with composite video out)
Choose this board if you want to mount the uIDE externally and you would like to have access to a composite video signal.
PCW Adapter "lite" (without composite video out)
Choose this board if you want to mount the uIDE externally and you do not require composite video. The VSYNC and VIDEO signals are still available on the board.Z80 shim / bus connector (LHS)
A Z80 shim card with the bus connector on the left hand side of the processor. Choose this card if you want to mount the uIDE adapter internally, or you need to keep your expansion port free.

Z80 shim / bus connector (RHS)
A Z80 shim card with the bus connector on the right hand side of the processor. Choose this card if you want to mount the uIDE adapter internally, or you need to keep your expansion port free.

If you are going for a Z80 shim, check that your PCW has a socketed Z80 and also check orientation of the chip. Check the space available inside your machine and choose the shim which best fits (I think the 8256 has enough space to accommodate left or right handed shims, but the 9512 needs the right handed shim because there is a capacitor in the way). Then double check!

I have ordered a small batch of cards (10 of each) from a Chinese supplier.


Again, please do not order from OSH Park as these boards are untested. I will offer the Chinese boards when I know they are OK (and order more).

So far I have 6 expressions of interest. I have some questions for you.


@greatwolf1283 (http://www.cpcwiki.eu/forum/index.php?action=profile;u=1460) : Do you want the LHS or RHS Z80 shim? Recommended: LHS for PCW8256, RHS for PCW9256.


@MaV (http://www.cpcwiki.eu/forum/index.php?action=profile;u=422) : Which adapter do you need? Choose from Z80 LHS, Z80 RHS (Recommended: LHS for PCW8256, RHS for PCW9256), Expansion port with video, Expansion port "lite". Do you want them fully assembled or just the boards?

@JonB (http://www.cpcwiki.eu/forum/index.php?action=profile;u=901)

I'm happy to go with just the boards.  My preference is for a right handed shim board.

I'm considering using 40 pin turned wire wrap DIL or SIP sockets, instead of the IDC headers for P1. They may increase both the height and price a little (plus neither appear to be available from Farnell at the moment), but I'm fine with both for my system.  Plus it means less soldering.  ;D

Looking forward to this.  Many thanks.

Thanks, Steve.


Check those wire wrap parts don't damage the socket on the motherboard. If they don't I may use them myself, because less soldering, and I can cut the legs to lower the shim. But to be honest, I'm not all that keen on producing fully populated boards because of the time it will take. However, there aren't that many parts and so far less than 5 people want populated boards.


Cheers
JonB


PS, I have published provisional board prices on Amstrad.ES:
I hope that is reasonable. I have yet to get the parts prices together (it is surprisingly complicated!) and put a value on the assembly time.


Don't forget, if you are using a Z80 shim you need a 40 way IDC cable (a PC IDE hard drive cable is perfect) to connect the uIDE and shim together. It is possible you can just solder the boards together, there is a lot of space inside the PCW, but I have not yet tried it out. (I will, though! ;) )

The pins on my prototype shim are square and 0.65mm thick. I found a datasheet for a wire wrap socket and its pins are also square, but they are .635mm. Better, but not by much. I have some turned pin headers here and they are .48mm in diameter. I think I will use these. :)

Check those wire wrap parts don't damage the socket on the motherboard.

<snip>

Don't forget, if you are using a Z80 shim you need a 40 way IDC cable (a PC IDE hard drive cable is perfect) to connect the uIDE and shim together. It is possible you can just solder the boards together, there is a lot of space inside the PCW, but I have not yet tried it out. (I will, though! ;) )

Hmmm, good point about the possibility that wire wrap parts may damage the motherboard socket.  All of the sockets on my machine are the bog standard non-turned pin parts.  I may just stick with your way after all for P1.

But... I may just use male and female IDC connectors on the uIDE and shim so that can simply plug together.  It would mean I couldn't later use a standard 40 pin IDC cable though.

The prices look fine too. :)

I have just ordered a bunch of 128MB DOMs to use with uIDE. These support 8 bit mode and LBA as required by the driver, and they are very small, suitable for mounting directly onto the end of the uIDE card with a 90 degree pin header.


You can have one with your uIDE card for an additional £4.

Wow, sorry, didn't see this thread before due to less time for the CPC at the moment, but was already writing with JonB via PMs.
I would like to order 2 boards!

May I ask what was the reason why you decided to use a DOM instead of a CF card? Sorry, somehow I didn't get it exactly.

A SymbOS IDE driver isn't a problem at all, I should be able to use the CPC SYMBiFACE II driver and just modify the port numbers.
Only problem is, that SymbOS doesn't support CP/M file system variantes beside Data, System and PCW single side single density. So if you use an IDE device with SymbOS on the PCW it has to be formatted in FAT12, 16 or 32 (which is also a reason why I would prefer a CF card interface - more data more fun :) ).

@JonB (http://www.cpcwiki.eu/forum/index.php?action=profile;u=901), I just answered your last PM as well.

Hi @Prodatron (http://www.cpcwiki.eu/forum/index.php?action=profile;u=13)

uIDE will work with some CF cards (not sure which, someone will have to try and let us know) but needs one of those IDE-to-CF card adapters that you see on eBay. However, a DOM is physically smaller (than a CF card plus adapter), looks neater and it supports power on IDE pin 20, which many CF card adapters don't (although having said that, there is a power supply on the uIDE board next to the IDE port for this reason, or you could modify the adapter).

The original concept was for a simple, cheap, easy to build generic IDE adapter to support CP/M machines, which are limited to 16 partitions of 8MB each, hence the "default" choice of 128MB DOMs. Although there's nothing stopping you from fitting a bigger DOM, of course.

Regarding your boards, which connectivity option(s) do you prefer?

One more point.


Having investigated the parts cost and likely assembly time, I decided that I can't offer these boards assembled unless I have at least 10 orders (of each board that people want). So far there are only 3 as most people just want the boards. Also @Audronic (http://www.cpcwiki.eu/forum/index.php?action=profile;u=1169), I do not wish to supply a kit of parts as it is error prone and time consuming.


So, if you want the boards assembled, please add the following to the board cost, which includes parts and labour:
Yes, there is a cost to assemble (my time) but it is minimal. I won't be retiring on this!

Post by: JonB on 19:12, 09 February 17
@Bryce (http://www.cpcwiki.eu/forum/index.php?action=profile;u=225), I'm waaay too embarrassed to say.


But since you ask..


I imported a mounting hole footprint but the hole was not on the normal layer for vias and pads, so KiCad produced two .drl Gerbers; one for the mounting holes, one for the vias and pads. When I uploaded the Gerbers to the maker's site, it errored out, saying there were too many .drl files (should be one), so I deleted one. Bad luck that I chose the pad/via .drl file! To completely not help matters, their web site generates a board render with a caveat that if you see any errors, you shouldn't contact them because the render is provisional. I spotted the missing holes immediately but assumed it was a problem with the rendering.


So anyway, these boards can be mounted, but not populated with any parts. Maybe I will mount them on a picture frame with "Fool" written below them!

Title: Re: Who wants IDE drives on the PCW?

That's why I prefer manufacturers that create the Gerbers for you. That way nothing gets lost.

PCBPool will accept almost any format, including: Eagle .brd, KiCAD .brd/kicad_pcb, OrCAD .max, DipTrace .dip and many others. You don't need to make the Gerber yourself, they create it from your board file.

They are relatively expensive, but after being burnt by manufacturers that delivered really shit quality after waiting weeks for the parts to arrive, I prefer to pay a little bit more for top quality and 8 day delivery.

They also offer features that many others don't, such as flexible PCBs, blind/buried vias, Aluminium Core, embedded RFID, etc.

I assembled one of the boards and connected it to a PCW8512 via a Z80 shim. So:

The ribbon cable is a standard 40 way IDE cable which came from a PC (hence "MOTHERBOARD" label, presumably for novice system assemblers).

At the other end of the ribbon cable, we have the uIDE-8:

 [ You are not allowed to view attachments ]

The DOM is connected via the coloured jumper cables because this being a prototype card, I have the IDE pad back to front / upside down. A proper uIDE will allow you to plug the DOM straight into it, so don't worry!


Also, because I have not received any of those little jumper blocks for setting the I/O address range, I have had to use wired jumpers for now.
Title: Re: Who wants IDE drives on the PCW?
Post by: JonB on 18:22, 18 February 17
The hardware side of things looks good. I ran the XTEST.COM program to retrieve the DOM's IDE Drive Identification data.


 [ You are not allowed to view attachments ]


This is a good test, because it demonstrates that the drive is sending data and the PCW is receiving and interpreting it correctly. Hurrah!


So, that's the good news. The bad news is that my version of CP/M Plus on the 8256 (v1.4) is not loading the FID driver file at boot, so I've started another thread to ask about this.

Nope. To fix it you need to have one half on the top of the board and one on the bottom.


I discovered this morning that it is do-able as you can see from the picture I posted of build 2. Tricky and time consuming. Fortunately it is only the first three boards from OSH (OMG how much??) Park that are affected, and I always intended to keep those for my own machines.

Jon,
 
Just looking at your notes on the Wiki.
 
Saw one thing, where you were explaining about copying files and user areas.
 
I hope this will still apply to your device, but note that any files in User 0 that are marked as 'System' should be visible to ALL user areas.   This is how CP/M normally operates.   I do this with disks normally.
 
Apart from that, I don't usually use the USER command, there is no need to.   If you're in A:, and you want to swap to user 1, you just type A1:.
 
The VERY handy NSWP utility will take care of a lot of these issues, maybe that should be part of your little software package.   Makes it easy to set the attribute for SYSTEM as well?

I am very interested in an IDE adapter for the PCW. But I'm not sure wich version is the best for me. Is it possible to use two or three devices at the expansion port? I also have an DK'tronics joystick and sound adapter and the CPS8256.
Title: Re: Who wants IDE drives on the PCW?
Post by: JonB on 22:16, 24 February 17


The adapter doesn't have an expansion through connection, so you should fit uIDE-8 internally with a z80 shim. This is how mine is connected, it leaves the expansion port unused.


It is technically possible to have a through port, but I haven't found a suitable parts supplier yet. You need certain edge connectors for this.


PCW owners with no additional stuff to plug into the expansion port may be interested in my z80 bus expansion card and CPS8256 clone, which are in development. See here: http://www.cpcwiki.eu/forum/nc100-nc200-pcw-pda600/serial-parallel-io-via-z80-bus-adapter/ (http://www.cpcwiki.eu/forum/nc100-nc200-pcw-pda600/serial-parallel-io-via-z80-bus-adapter/)

Hello Marcus


Yes, you may be able to use other IDE devices. I only guarantee it will work with the DOM I offer, because I cannot test with every CF card on the market. Some CF cards are not compatible, see the wiki page I wrote for details: http://www.cpcwiki.eu/index.php/UIDE_Universal_IDE_adapter_cards_for_Z-80_computers


uIDE does not support CD-ROMs or other devices. Someone would need to write a driver for that. The key compatibility requirement is IDE-ATA 8 bit mode, which DOMs and CF cards do support, but I am not sure that CD-ROMs support it. I suspect there are some timing considerations too, which might explain why some CF cards don't work with it.


You are welcome to try a CF card with adapter. Please let me know if it works or not, then I can update the compatibility list in the Wiki. But I still recommend you use a DOM.


I have recorded your order.

Well, so far the board looks OK and the two 40 way sockets are oriented correctly. I've done some continuity tests and so far nothing wrong. Even swapped out the 688 for a known working one, tested the '02 and discreet inverter circuit, all good. Next up is write some test programs on the PCW, but it is busy transferring software via slooow serial. I'm building the IDE download image described on the Wiki page.


You can use uIDE-8 with a PCW9512 as well. And don't forget, there is uIDE-16 for the CPC6128 as well, so you don't need to acquire a new box specially. Although, to be fair, a PCW8xxx machine is going to cost you pennies. Last one I bought was £15. And that was on eBay - they are unloved, which is one reason I produced uIDE-8. If only I could find out why it's not working!

@JonB (http://www.cpcwiki.eu/forum/index.php?action=profile;u=901)

Quick question about the uIDE-8 BOM.  C1 and C2 are listed as radial ceramic caps, but your notes say tantalum preferred.  Assusming they are just for decoupling, wouldn't you want non-polarised caps?  i.e. not tantalums.

Another wrinkle for self builders.


Due to a problem with the circuit implemented by R5, R6 and Q1 (a single NOT gate which worked for the prototype and first production builds but only if a certain brand of 74LS02 was used), I have had to remove these components and substitute them with a single inverter IC - SN74LVC1G04DBVR, which costs 23p from Farnell: http://uk.farnell.com/texas-instruments/sn74lvc1g04dbvr/ic-inverter-single-smd-sot-23/dp/1287591 (http://uk.farnell.com/texas-instruments/sn74lvc1g04dbvr/ic-inverter-single-smd-sot-23/dp/1287591). The BOM on the WIKI page is updated.

This tiny IC should fit directly on the Collector / Emitter pads of Q1 if oriented correctly; then two jump leads are needed to connect pins on the IC to nearby pads.

I ordered a bunch of these ICs and will try it out. If successful I'll post details of the fitting method.

(If you ordered an assembled board, this doesn't affect you, because I'll fit it myself.)


Oh, the joys of prototyping and production...  ::)

Update on the single inverter fix for TI '02s - it didn't work.


So I took a look at the datasheet for the Mitsubishi part and discovered it has a very high propagation rate (for an LS part), so I am now thinking I should try a high speed ALS '02.



That's next on the list. Please don't order any parts from the BOM until I know what works and what doesn't...

[Edit: Some 74ALS02s arrived today but they didn't work, either. They are even slower than the LS02 in my prototype, so I have had a good look at the propagation times for various 74--02s. There is a huge range of timings between the different manufacturers, but it is looking like the part should be a 74F02 ("fast"). I'll get one and try it.]

Well, turns out you can use cpmtools to access files on the uIDE image, so I have updated the wiki page to show you how. It also has the uIDE download files, and shows you how to get the uide image onto a CF card or DOM.


With these instructions and utilities, you can copy stuff to / from your PCW's uIDE drive without using a serial interface.

Title: ANNOUNCEMENT
Post by: JonB on 13:05, 11 March 17
Hi all

I have now solved the 74LS02 problem with the uIDE-8 board and as a result will soon be building them to send to those who asked for assembled units. I will reach out to you all (including board only guys) via PM to ask for order confirmation of the items you wanted and give a PP address for payment. Self builders should use a 74F02 for U2 and the BOM has been updated accordingly. The transistorised inverter stays as-is.

While you're waiting, please review the information on the wiki page as there are some things you can do now to prepare for your board (such as enter the BASIC program to get the driver onto a floppy disk and - if you are not having a DOM - sort out a transfer cable to get the image onto your CF card or DOM). You should also check you have a 40 way IDC cable to connect uIDE to your ExpensionPort adapter or Z80 LHS Shim. As I explain on the wiki page, this is just a bog standard IDE cable such as you will find in any old PC.

Too right! There's nothing worse than thinking all is fine and dandy, then discovering a so called "standard" part insn't. So the lesson here, kids, is "always read the datasheets"!

Well done Jon.   :)

Just curious, what is the difference between the F and the LS part that makes the difference?

<edit>
Forget the question - I should have read the updated Wiki first  :doh:
</edit>
Title: Re: Who wants IDE drives on the PCW?
Post by: JonB on 22:45, 11 March 17
For the benefit of our thread lurkers, the answer is "speed", or more correctly "propagation time". The F part is about 4 times faster than the LS part. My prototype was built with an uncommonly fast LS part made by Mistsubishi. That was very lucky, because if I couldn't get the prototype going I wouldn't be offering them to other people.


Anyway, it's a great relief to get to the bottom of this and move forward with the project.  :D

Hello Jon,

great job, the uIDE drives very well with my PCW 8512!  :)
First I had problems because of the CP/M version J14GCPM.EMS, but with J15CPM the XDRV.FID works.

A question:
Does anyone have a German version of the file J15CPM? Unfortunately the keyboard layout does not fit.

Yeah, put it in your PROFILE.SUB on A:, but call C:SETKEYS for speed.

That's what I do in mine:

Code: [Select]
C:SANSERIF
C:SETDEF M:,C:,* [ORDER = (SUB,COM)]
C: SETSIO 9600 HANDSHAKE OFF

The first line sets a nice font.
Second sets up the search order for COM and SUB files: M: first, then C: then default; SUBMIT files first, then COM files.
Third line sets up my serial port adapter.

Because the COM files are on C: it is much faster.

Hi Sucram


Could you share more of your experience with uIDE? What type of bus cable are you using?
Title: Re: Who wants IDE drives on the PCW?
Post by: JonB on 18:41, 26 March 17
It looks like the photos I put on the Wiki page showing the right way to connect the uIDE to a PCW are not consistent with the cards I sent out. This is because I used a prototype in the photos.  :picard:


So, I have taken those shots down temporarily, and will put some new ones up soon, when I have a built uIDE-8 to show.


Big thanks to GeoffB17 for pointing this out to me!

Hello Jon,

sure, I will describe my experiences with the uIDE:i am using a normal 40pin cable for PC hard drives, as you see at the picture.First I had connect the uIDE at the other connection of the cable, but that doesn't work,  I think because of the cable length. The cable should be short I think, about 15cm.

[attachimg=1]

Meanwhile I use J29CPM, the file transmission I have changier from EMT to EMS. This version of CPM can be started from my GOTEK-USB with HxC firmware and the hardware driver works.

[attachimg=2]

In order for the new drives to be detected, they must first be addressed once.

[attachimg=3]

The uIDE Drive is really fast, like the RAM.
With xformat new DOMs can be formatted very quickly and comfortably.


[attachimg=4]

It is really a great work, I hope SymbOS will support the uIDE soon.


Greetings from Germany,
Marcus
Title: Re: Who wants IDE drives on the PCW?
Post by: GeoffB17 on 20:27, 26 March 17
Yes, yes!


Got my uIDE working just now, after some problems due to the instructions being a bit out of date, and I'd got a couple of the utilities from an early version.   Thanks to Jon for 'telephone support', but all working fine now.


Just need to sort through all the 'stuff' on the DOM, a lot I already have.   Still, not exactly short of space now!


I'll do some testing regarding compiles, etc, and report further.


Seems like the version of NSWP I have is OK with the drive capacities, but I need to keep an eye on that.   Maybe some file sizes cause confusion, or so I've noticed on the Joyce emulator.


By the way, my IDE cable is fairly long, maybe 40cm+, but it seems to be fine.   If it's working, I'll not mess with it.


Thanks again, Jon.

Thanks Marcus! Yes, Prodatron (author of SymbOS) already said he would support uIDE on the PCW under SymbOS (also on the 6128 I imagine, but he wants to do the PCW version first). I am waiting for some parts before completing his boards. I like your GoTek installation, by the way. Looks really tidy!

About the cable length. I have made up 50cm cables that worked OK with expansion port adapters. But as your installation is with a shim, I imagine it will be internal, so you can stick to short lengths. In general though, I agree that it's wise to minimise the cable length, as there's no termination (or buffering) on the board. Maybe your cable has some poor connection on the outer socket? I found that the old IDE cables I have lying around are quite stiff due to age, and this may cause their sockets to work loose. Try clamping the suspect socket in a vise to tighten the connections.

Geoff, I'm glad your boards are working now. I have updated the photos on the Wiki page that caused the confusion, although they show uIDE-16s connected to the PCWs because I have no built uIDE-8s to hand that are not prototypes. Not to worry though; the uIDE / bus cable orientation is now shown per the uIDE-8 "production" boards.

sucram, I am a little concerned that the XFORMAT.COM program is corrupting the usage string. Is this because your PCW is German?


Also, you might notice that it shows 16 devices (partitions). It's supposed to give you 16 IDE partitions, but the PCW only allows 6 :( and moreover, it takes one away from you if you plug the CPS8256 serial adapter in.


To add insult to injury (as we say in the UK), LocoScript gives you C: D: E: F: G: H: I: J: K: L: (but stops there). Odd, no?

Yes, the strange display with Ä and Ü instead of [ and ] is because of the German language, the character table is a little different.


The number of partitions is enough. 😀

Anyway, I thought I'd post a few pics for all to see.

To start off, here's the uIDE8 in the LSI-M3 (the mainboard slides out of the case).  The uIDE is attached via a shim board and is resting on top of the RAM chips:

Hello -B-

Start by reading the wiki page (http://www.cpcwiki.eu/index.php/UIDE_Universal_IDE_adapter_cards_for_Z-80_computers) I wrote. It should answer your questions and explains the capabilities and limitations of the device.

At the moment I have boards but not enough components to build finished items (I'm short of the edge connectors used by the adapter). If you want to use a Z80 shim I can probably build a set, because it doesn't use the edge connector. I strongly recommend you buy a DOM (£4) as well, because it has the driver on it, although you can download an image and put it on another IDE device.

PM me when/if you are ready to proceed.

I have now run out of the v0.5 "blue" uIDE-8 boards. All I have left are the v0.4 "red" boards, and these have a couple of manufacturing defects which are easy to correct.


I added a new section to the Wiki page to explain here:


http://www.cpcwiki.eu/index.php/UIDE_Universal_IDE_adapter_cards_for_Z-80_computers#uIDE-8_.22red.22_boards


These minor issues aside,  they work exactly the same as the blue boards.


Cheers
JonB

@JonB (http://www.cpcwiki.eu/forum/index.php?action=profile;u=901)




I was wondering if I put a Box header (50 Pin) on the PCW Z80 Bus Adapter
Instead of the Edge connector. And an Appropriate short cable from the PCW.

Sure, Ray.

They are only wire connections after all. It's a tricky job, removing a 40 way connector though, unless you have a desoldering station. But how will you connect it to your PCW, if not via the edge connector? An alternative might be to get a Z80 shim (http://www.cpcwiki.eu/index.php/UIDE_Universal_IDE_adapter_cards_for_Z-80_computers#Fitting_a_Z80_shim_to_the_PCW_8000_series). Open up your PCW and see if the Z80 is socketed. If it is, you are in business.

Cheers
JonB



PS, I see you are not using the video circuit (missing trimmer pot). None of the components in the video circuit border are needed by the interface.

Is there a Schematic of the 6128 Z80 Bus Connector, and the PCW Z80 Bus adapter Please

I was thinking of using the Cable shown below as i have nil stock of the 50 Pin edge connectors


Thanks    Ray

That cable will work.


But make sure you have the uIDE oriented correctly.

Hello,


Hopefully Jon will reply, but the bits you show look like the same one I have, the larger card is for the DOM etc, the smaller one fits onto the interface connector.   The second one is NOT the card for the Z80 shim thing.   Have you been sent the wrong bits?


Check the Wiki page for pics of the various bits/alternatives.

Hi Sebastian


I think you ordered the external port adapter with composite video:

Don't forget that you need to patch the boardto get the video circuit to work:

You could also make a cable up with one of these: http://www.ebay.co.uk/itm/262700376755 (http://www.ebay.co.uk/itm/262700376755) and http://www.ebay.co.uk/itm/252702186367 (http://www.ebay.co.uk/itm/252702186367) but it would be more expensive.

Finally I got my uIDE working with SymbOS and an old FAT16 formatted 2GB CF card  :D

[attachimg=1]

Thanks so much for this great PCW hardware, JonB!!!  :D :D

I was a little bit lazy during the last monthes, but after some testings last weekend on a vintage computer meeting and buying a CF2IDE adapter it was working directly with the first try!
Now I don't need to swap discs anymore after booting SymbOS, yeah!

Now how about the 6128 SymbOS drivers?  ;)
Title: Re: Who wants IDE drives on the PCW?
Post by: Prodatron on 19:08, 08 September 17
Well done Prodatron!
Thank you :)

Now how about the 6128 SymbOS drivers?  ;)
For the next SymbOS CPC version I will introduce a driver system like we have for SymbOS MSX. Currently the drivers are fixed embedded into the code, this will be changed in the next version. Then we can have a SYMBiFACE II/X-MASS IDE driver, an M4Board SD card driver, an uIDE driver, Albireo USB etc. etc.
The uIDE driver for the PCW was exactly the same like the SYMBiFACE II driver just with different port addresses (and more optimized 8bit addressing). So a uIDE-16 driver for the CPC should be done in a few minutes :)
Title: Re: Who wants IDE drives on the PCW?
Post by: JonB on 19:12, 08 September 17
It's as I thought... IDE drivers are all basically the same apart from the port numbers.


Interesting though: I wonder of these existing SYMBIFACE drivers would work if you reconfigured the uIDE-16 port address to match the other IDE device?
Title: Re: Who wants IDE drives on the PCW?
Post by: Prodatron on 19:21, 08 September 17
Here is a short video showing SymbOS PCW playing videos and loading apps from a FAT32 formatted CF card via the uIDE interface. Starting from 0:56 you can see the interface itself connected at the back of my PCW.

https://www.youtube.com/watch?v=0t4ud6GYLLI (https://www.youtube.com/watch?v=0t4ud6GYLLI)

The video files are 4colour ones encoded for the CPC and have to be downrendered to 2colours by the Z80 in realtime. Also don't forget about the very special way how the PCW is organising its video memory ("roller ram"), which slows down the plotting of linear bitmap graphics.
But this is just a demo to show, that it's working :)

There is one issue left:
It seems, that I have to initialize the uIDE interface somehow. Currently it only works, when I start XTEST.COM first e.g. with the -im option before I boot SymbOS.
There are currently two other little bugs in this PCW version of SymbOS, if this is fixed I can release this new one.

Good idea! I didn't connect it yet to the CPC, but I will try extactly this as soon as I have done it!

Assuming SYBIFACE works in 8 bit mode if course. If it works the IDE interface in 16 bit mode you won't be able to use uIDE with it.


Now - about initialising the IDE device that is plugged into the uIDE card - you need to set IDE 8 bit mode and no caching, like this:


Code: [Select]
;-----------------------------------------------------------------------------
; IDE interface registers - Base address 0C8h for PCW
CF_BASE equ 0C8h ;IDE I/O Base address
CF_DATA equ CF_BASE ;0C8h $10 dataport
CF_FEATURES equ CF_BASE+1 ;0C9H $11 reg1port
CF_ERROR equ CF_BASE+1 ;0C9h $11 reg1port

CF_LBA1 equ CF_BASE+4 ;0CCh $14 reg4port
CF_LBA2 equ CF_BASE+5 ;0CBh $15 reg5port
CF_LBA3 equ CF_BASE+6 ;0CEh $16 reg6port


;-----------------------------------------------------------------------------

;-----------------------------------------------------------------------------

out (CF_FEATURES),a ;

ei

xor a ;
ret ; done


I'm not sure if you will need the ei/di instructions in SymbOS. I found the PCW driver drops bytes if I exclude them, due to the clock interrupt. Also, the PCW driver polls the IDE device so there is a "wait until not busy" routine called prior to each IDE operation that ensures the device is ready to receive the operation command:

Code: [Select]
;-----------------------------------------------------------------------------
; Wait for IDE device to be ready
cfWait: push de
ld d,CF_WAITRETRY ; load retry counter
cfLoop: di ;
in a,(CF_STATUS) ; get IDE status
ei
ld (laststat),a ; save it down
and CF_MASKBSY ; check busy bit
jr z,cfEnd ; if clear, drive is ready
dec d ; otherwise decrement retry counter
jr z,cfTout ; if zero, drive has timed out
jr cfLoop ; otherwise loop back for retry

cfTout: ld a,CF_TOUT ; timeout: load rogue value
jr cfCcy ; jump to abnormal return

cfEnd: ld a,(laststat) ; retrieve status
and CF_MASKERR ; check error flag
jr nz,cfErr ; error exit if set

cfOK: scf ; return with carry set
pop de ; restore
ret ; done

cfErr: di ; error:
in a,(CF_ERROR) ; get error register
ei ;
ld (lasterr),a ; save it down

cfCcy: scf ; clear carry flag
ccf ;
pop de ; restore de
ret ; done

This code is from XTEST.COM which is currently the only 6128 CP/M Plus program that can access an IDE device via uIDE-16. I have not been able to work out how to integrate the IDE driver into the 6128 CP/M Plus implementation. Use the 6128 version of XTEST.COM in CP/M Plus to prove that the uIDE-16 card is set up correctly before trying it with SymbOS. It is in the downloads section of the uIDE wiki page.

Oh great, thanks for this! This already should answer my question regarding initialization (the SYMBiFACE II is working in 16bit IDE mode like all MSX IDE devices, too, and the X-MASS is switching to 8bit IDE mode byitself). Let's try it...
Title: Re: Who wants IDE drives on the PCW?

Btw, is there a reason for disabling the cache?
Is the uIDE hotswap-capable? (most other IDE interfaces aren't AFAIK)

Now - about initialising the IDE device that is plugged into the uIDE card - you need to set IDE 8 bit mode and no caching
Seems to work fine now, no need to start XTEST anymore before SymbOS boots, thanks a lot! :)

No particular reason. I don't think caching would make IDE transfers any faster, though, because the IDE device will always be quicker than the PCW. So I feel it is safer to turn caching off, just in case. Besides, the PCW has no shutdown as such - doesn't need it - so people hit the power switch. Not a good thing to do with caching enabled!

I think the X-MASS works in 16 bit mode, but presents the two bytes of each 16 bit word to the PCW sequentially and this is done by its hardware. It's not the only IDE solution (for 8-bit machines) that does this; I've seen a few rather elaborate designs that do the same. However, 8-bit mode is part of the CF IDE spec, so should be supported by the majority of cards (DOMs too, which I tend to use on the grounds that they seem to always work and don't require an adapter to connect to uIDE).


Using IDE 8-bit mode also made uIDE very simple and easy / cheap to build, and these considerations formed part of its design objectives.

@Jon (http://www.cpcwiki.eu/forum/index.php?action=profile;u=659):

X-MASS operates in 8-bit mode. The CPLD programs this at power on and holds the CPC in reset until the device accepts it. So just like the uIDE it requires a device supporting the CF-IDE spec. If I try to enable 16-bit mode with X-MASS I see half the data. (8 bits of each 16bit data).

Symbiface 2 operates in 16-bit mode. It doesn't program anything at power-on and assumes the device is in 16-bit mode from the start. Reading from the data port returns the first byte and then the second. It operates similar to G-IDE but I think the design is independent. Most HD's I've tried don't support 8-bit mode even though the ATA-1 spec mentions it.

Yes, that's exactly how it is. Btw, I have a 10 years old 16GB SanDisc "Extreme" CF card, and it isn't detected on the PCW with uIDE by the XTEST tool and SymbOS. Maybe even some (larger?) CF cards don't support the 8bit mode, too? Anyway all of my smaller ones work fine, and it seems, that it's the same for all DOMs.
Title: Re: Who wants IDE drives on the PCW?
Post by: JonB on 11:27, 10 September 17
I stand corrected...  :)


...and by the way, that's one reason I recommend using a DOM with uIDE. However, my use cases are all CP/M based, so a 128MB DOM suffices (also being jolly cheap).

It is possible that the larger CF card needs additional configuration.
I will try and make a test that can be run to confirm it.

Does this mean that you can use devices that only support 16-bit on the uide, but only have access to half the capacity? (And end up using the drive in a way that would be incompatible if e.g. a PC tried to read a symbos fat partition it using standard fat drivers?)

uIDE operates in 8-bit mode. No wasted bytes. However, when formatted, it cannot be read by a PC directly because the format is a custom one that CP/M can support natively.


You can use CP/M Tools on Windows or Linux to read and write files from / to a uIDE formatted drive, and full instructions are provided on the Wiki page (as well as a download).


To save you from searching for it, it is here: http://www.cpcwiki.eu/index.php/UIDE_Universal_IDE_adapter_cards_for_Z-80_computers .

Hi Sebastian


You haven't got it working yet?  :o


The download link to the correct version of CP/M Plus was on the uIDE information page all along. That's why I asked everyone to read the whole page (which took more time to write than the uIDE did to design, nearly).


Anyway, click this link and your browser will download the file: http://www.cpcwiki.eu/forum/nc100-nc200-pcw-pda600/cpm-plus-1-11-1-5-download/?action=dlattach;attach=21886

Yes it took me a wile, i was missing some components that i couldn't source locally ended up purchasing them online but was slow.
Of course i read the whole file on the wiki and very impress how much documentation you worked out.
For some reason when i got to this part couldn't understand that the .EMT files where the os itself i was expecting to find a .dsk file or something like that.
Now managed to build a bootable floppy including all the tools and the ide device worked perfectly the first time !.
Thanks for all!

JonB i have another question theres an ide board for the cpc 464 ?.

No, but there is one for the 6128 called uIDE-16 (because the 6128 uses 16 bit I/O addresses when it performs IN or OUT).

This would certainly work on the 464 (in 16 or 8 bit addressing mode).

If the 464 is using 8 bit mode you can use a normal uIDE-8 but you will probably need to connect it with a Z80 shim.

However... there are NO drivers for it other than for SYMBOS.

If someone can sell me a fully assembled board (sorry i have no soldering-skills) for the MotherX4, i will try to integrate a driver in my CubeMDOS.
(I'm using a CPC6128)
(PM me)

Just preparing a PCW uIDE-8s for someone...

These are the red boards and I have three of them left.

Experimental Schneider adapters and uIDE-8/DOM


  [ You are not allowed to view attachments ]  


The idea is, you provide a cable to go from the Centronics style adapter on the back of the Schneider Joyce to a 50 way female IDC socket. This plugs into the adapter's header, then you connect the uIDE-8 to the adapter in the normal way.

The Schneider-adapter cable should be fairly easy to get hold of. They used to be used for connecting SCSI drives to computers. Something like this would do: https://www.ebay.co.uk/itm/270837227488

This is great! I would take one or two of them to. Because my PcWs have Centronics ports too.  :) :) :)

We'll have to wait to find out if they actually work, though. Should do, but I don't make any guarantees unless proven. But this is why I sent the additional adapter (the blue card) to the buyer - it has the IDC header on the component side of the board, and both boards use unboxed headers so you can fit the cable either way round without worrying about the IDC plug's key orientation.

I've proposed he tries both adapters:


GUNHED, I have two uIDE-8 boards left, assembled, plus adapters. After they go, I am down to some prototypes (working of course) and uIDE-16s running in 8 bit addressing mode. As demand has dropped off quite a bit, I don't see myself getting more boards any time soon..
