Title: MultiFace II clone
Post by: talrek on 20:36, 11 February 15
Hi everybody,
i must be crazy but i would like to build a MF2 clone since we now have all we need to make it...

First, i thought about a compatible MX4 format board. I tried, but i must admit, there is a lot of components, and 5x8 cm is small for a MF2
I'll try to minimize the size by using SMD components (except for Gals), but i not guarantee it will be the size of a XMEM or XMASS

First, i'm going to make the pcb and i'll show the 3d result ;-)

price will be 30 euros without cable, add 5 euros for either a edge connector or a centronics one

Hi Talrek,
I'm in for one ;-)


Lattice GAL16V8B IC 10pcs | eBay (http://www.ebay.fr/itm/Lattice-GAL16V8B-IC-10pcs-/230255582249?pt=LH_DefaultDomain_0&hash=item359c4d5c29)
Not the cheapest but the seller seems ok, 37.5e for 60 units to build 20 MF2 clones.

Thank you. I bought some IC's from them , they are OK.

Already noted in the other thread, but I'm interested!

I'm surprised it's such a squeeze as I figured the original MF2 PCB is fairly close to MX4 size already... but I will leave that to the expert!
Title: Re: MultiFace II clone
Post by: Bryce on 23:13, 11 February 15
I've an original MF2 here. It's only a little bit bigger than an MX4 format and it has to have that big edge connector in the middle. It should easily fit on an MX4 format.

Bryce.
Title: Re: MultiFace II clone
Post by: talrek on 11:25, 12 February 15
Without the edge connector, the size is 9,6x6,3 cm.
The mx4 format is 8x5.
There is a difference of 20,5cm^2
Hard to believe but it's true

So I must find a way to find space.... But even with smd it's hard
Title: Re: MultiFace II clone
Post by: Bryce on 12:25, 12 February 15
If you go SMD you can put parts on both sides of the board and save major amounts of space.

Bryce.
Title: Re: MultiFace II clone

Yes you're right, i'll try that.

great !!!


Title: Re: MultiFace II clone
Post by: TFM on 21:22, 12 February 15
I would take one - even if the MF2 is not powerful enough to deal with FutureOS.  :laugh:

Since you own an original MF2, could you please tell me the resistor network's value ?  :D

For the price i must see, but it will be more than 24 euros, there is at least three GAL16V8...


A Multiface? The holy grail!


And if you get it working for the CPC I'm sure Spectrum owners would also be interested. They change hands for a fortune on Ebay so you can be sure of a good demand!

I'd have implemented it all in a CPLD instead, then it's just one chip instead of 6. :) Well done getting it all to fit, anyway!

I'd buy one but my MotherX4 is already full...

Buy another MotherX4 then and add it to the passthrough, That was my plan as mine is also full and I have expressed interest in this card and I am kinda sense a RTC may not be that far away either LOL 
Title: Re: MultiFace II clone
Post by: pelrun on 03:01, 13 February 15
I'm waiting on some PCBs to get here from China, then I'll have an FPGA wired to the expansion bus. May as well just implement an MF2 myself at that point :)


(damn, I wish I put a couple of buttons on that board now, there was plenty of space for them...)

Well, I chose to stay as close as possible to the original design. Due to the mx4 size I had to modify the placement and use smd, it is the only compromise I'm ready to do to keep original retro spirit. [emoji1]
Though a cpld is a very good idea to gain a lot of space.

No problem. I'll check at the weekend. I also have a Spectrum MF, so I can check stuff on that too if needed.

Bryce.

P.s. I don't actually need either of them, so if anyone really wants to own an original then make a reasonable offer.
Title: Re: MultiFace II clone
Post by: talrek on 13:29, 13 February 15
Ok so here is the details :

i'm going to make 10 pieces first. Since it is the first batch i need to be sure it works well, before to invest more...
Second batch (don't know how many) just after.

For the moment i've counted 8 reservations.

2 left.

Price will be 30 euros in MX4 format.
If you want a cable add 5 euros either edge connector or centronics.

I will edit the first post.

IIRC each model of Speccy required a different Multiface but perhaps it would be possible to design an all in one solution.

Other MF2 software has been done before, so you should be able to call ROM software I guess? The MF2 has 8K RAM that you can put code in to be called when it is paused. In particular tearaway looks cool (CPCRULEZ &#9733 APPLICATION &#9733 DIVERS &#9733 Tearaway: The Informer{UK} (http://cpcrulez.fr/applications_util-tearaway-the_informer.htm)).

There are loadds of other cool things you could do though:

. A debugger that is used with a RAM or ROM expansion and sits in higher memory (>128K) or ROM allowing you to debug the whole of the first 128K.
. A menu that allows loading/saving directly to SNA files (on hard disc, preferably).
. A system that allows directly loading/saving a SNA and then optionally boots back to symbos and starts again where you left off...

In theory, if symbos allowed selecting of image files for the HxC, it would be really cool to do the third option because you could load up a game to the HxC, then have symbos save its current state and reboot automatically launching the disk when restarting. Using the MF2 games could then be saved in SNA format and when you're done playing symbos could resume exactly where it left off. Later the SNA loader in symbos could be used to load up the saved games directly from Symbos. Something like this was discussed some time back, but I forget in which thread. It requires a lot of stuff to be done in symbos though (saving/loading state, HxC image selection, automatic booting of disk software) as well as the new MF2 code.

I am really gonna need to get a 2nd Mother4X for my machine. The one I have is already full with, from front to back, X-Mem, X-Mass, PlayCity & Mini Booster. @TotO (http://www.cpcwiki.eu/forum/index.php?action=profile;u=290) : I assume that that multiple M4X boards can be chained together, and if so can they be ordered with the correct 50 pin female to female ribbon cable? Is the 5v supply passed backwards to any additional boards, or would I ideally need to provide another 5v supply to the 2nd M4X for the Multiface Remake, RTC and whatever other boards come alone in M4X format?


I love to see a new standard coming along, it makes the new expansions options so very much neater.

X-Mass and X-Mem, well these are always in use.
PlayCity. OK again always nice to have some 6 channel tunes playing in SymAmp
MiniBooster, has become my DSK Transfer device of choice, so much easier than the HXC and SD cards etc. *

*OK, the HXC is still essential for games and DSK's that are have *unusual* sector layouts etc that the minibooster just cannot handle.

Minibooster is cool, but only works once in a while for me. More often the PC - CPC connection just don't work. So I use the HxC instead. So switch the SD Card is a task that even I can perform quick.  :laugh:

I don't have an HxD, and I've still not gotten far enough with my Gotek firmware to use it, so I have to resort to my tape cable to transfer dsk images. Drives me mad that I can't get a full disk image across the minibooster before aft and writedsk crash on a corrupted byte.


So I just spent two days bashing my head against cpctools trying to get AFT to compile (being forced to install Visual Studio just to get a version of the libdsk.dll that I can link to and fighting CMake for days just like every other time I encounter a project that uses CMake makes me a very unhappy person.). Hopefully now I'll be able to make some robustness improvements.

The 5V rail would be parallel across the two MX4 boards, so only one supply would be required.

If only there was one more mounting hole near the front of the MotherX4, then you could use a few long spacers and stack the second board above the first.

You should arange them like that and does the link from the passthrough connector?

[attach=2]

If you really want to make a Lego tower with them, I should provide you a second board with simple pins connectors on both sides.
So, you will be able to use the 4 holes to do what you need for your work. (your CPC mainboard make that useless)

yes. The Amsdos ROM in the plus needed different code in the multiface. The only difference is the MF ROM tho.

Also,if you fit parados in your plus you need the CPC multiface and not the plus one.

Do I lose anything if I go for a CPC Multiface instead of the plus one? Also which version is compatible with AMSDOS Firmware 3.12 ?  (This is the basic original Amstrad CPC6128 coupled to firmware 3.15).


I'm trying to get the best compatibility with games on my plus, I'm using a parados cart at the moment, only because I got fed up with the basic / burning rubber menu on the original cart.

I don't need to use parados really as I've got a hxc floppy emulator instead of a real external drive.

I've got a Cartridge on the way with Dual Roms in it, it contains PARADOS 1.0 and AMSDOS Firmware 3.12, I was told it is the original Amstrad Basic with a 3.12 firmware (100% compatible with all games).

I've got a normal cpc 6128 (original rom not parados) with a multiface and it would be nice to load any multiface saves from that up on my plus.

So I'm thinking I'll need a normal cpc multiface with the centronics cable if it works with AMSDOS Firmware 3.12 for best compatibility between both machines and games.





Title: Re: MultiFace II clone
Post by: TFM on 19:18, 19 March 15
The source of the MF2 ROM is available, so - if somebody got the time - it probably could be patched to work with CPC and Plus.

that is what I am hoping will be done in time for this release. I don't fancy ROM swaps all the time between the plus and just CPC.
Title: Re: MultiFace II clone
Post by: TFM on 16:02, 20 March 15
Damn right! So question is: Does the MF2 ROM for the Plus also work with the CPC? In this case we could just use the Plus version.

Title: Re: MultiFace II clone
Post by: The Last Bandit on 16:19, 20 March 15
Think the difference between the two is due to changes in the location of various AMSDOS routines MF2 calls. So the ROM for the CPC+ version wouldn't be backward compatible.


Put both ROM versions on the EPROM and jumper/switch to select between unless there a register that can be read to identify the machine type on startup and auto select.

no, they are not interchangeable.
Title: Re: MultiFace II clone
Post by: TFM on 17:45, 20 March 15
Well, in this case, for a proper redo of the MF2 we should make a ROM compatible to both: CPC and Plus.  :)

That would be cool :) What if you have both machines, do you need two or is there a converter to change from normal connection to centronics connector for the plus?
Title: Re: MultiFace II clone

You can get adapter cables working in both directions. In general the Centronics plugs are much more reliable.  :)

I guess you do pretty well. You can assemble it and see how much space is left. A plus detection only take few (20) Bytes. At work here... I have limited CPC abilities.  :)

As I understand it, the mf ROMs make direct calls to amsdos to load and save etc. In the plus some of these routines changed in location so the calls fail. The new ROM would need to know what machine it was in, and call amsdos accordingly. Unless of course I heard wrong and the above is total garbage.
Title: Re: MultiFace II clone
Post by: TFM on 22:13, 05 April 15
In this case it would be better to check the DOS version independent of the machine. Because Plus Users may use 0.50 Amsdos or Parados or so.  :)

I bought it on Amazon, but now it says delivery last date : May 5... I think the seller is in china, but it use another adress and he answers in French... argghhh

But instead losing my time, is there somebody here to program the 3 Gals ?
I send the Gals, and the person send it back programmed.

Of course i pay for the shipment  :D
I will then be able to test it, and when the POW (Proof Of Working) is made, i will build the 9 others (i have all the parts, but don't want to waste my time if there is an error)

Thank you !

Hello everybody  :D
Thanks to dxs, i received today some programmed gals
I tried them as soon as possible... and... It is official MultiFace2 clone on MX4 rocks  8) 8) 8)

It works well, i tried it on a cpc6128 and a plus one and it works fine so far.

I'll try to take pictures tomorrow (my daughter will do) because i broke my left wrist, and it becomes hard to solder with one hand  :'( :'(
I will solder now the 9 remaining as fast as possible, and iwait to receive my gal programmer.

I have  connected : XMem + XMass + MF2. Everything works.
I tested (the 3 connected without power supply on mother X4) :

1)Add Airwolf.rom in rom 03, with RMA in the xmem
2)reset
3) |airwolf from xmem --> runs well
4) Use "stop button" on multiface, "save", "program", "disc" -->new name on disc "airzolf"
5) reset on multiface
6) run "airzolf" --> game running
7) reset multiface, stop multiface, then chose "return" to make the mf2 invisible
8) run "airzolf" it doesn't work because the mf2 is invisible !!!! (normal)
9) reset mf2 , the mf2 is visible again
10) run "airzolf" --> works again...

Guess what  ;D ;D ;D ;D It seems to work all together for now. But i'm sure guys you will find something because i can't test everything i think.

OK, Now a question.....


Once my MF2+ arrives I hope to start doing yet more Cart Conversions. this time I'll modify the process a little.


1. Load the game on the Plus.
2. if controls are customisable set the game up to be fully 'joypad + P' compatible
3. Freeze and save the game to disk.
4. Use anti Multiface to create a loader than does not require an MF2 present
5. Convert to DSK
6. Convert to cart with @arnoldemu (http://www.cpcwiki.eu/forum/index.php?action=profile;u=122) 's tool.


Now the question....
Is there a way to load a multiface saved image without the screen distortion during load, or at least hide the screen (all black) until the game is fully loaded?


if not then so be it, I guess I will just create ugly carts!


I also plan on coding a simple Basic Joystick controlled menu for the DIZZY games, to create a couple of DIZZY Compilation carts, one for the 7 games, and one for the spinoffs. This menu will be in basic so don't expect too much -   No snazzy colours or rasters


Any thoughts on the Multiface loading plan let me know. (Remembering I am no coder - Unless you mean Basic)

OK The MF II remake arrived today. And a wonderfully well made piece of kit it is too. Oddness however is that although it works perfectly on my 6128 with Tape Mod, it does not work on my Expanded 464plus


In theory these 2 machine are identical - Both have 128k, Both have Disc Interfaces, both have tape interfaces. But on my 464 plus when hiding the MF II and returning to Basic, |tape or run" will both crash the machine, or reboot it.


On the 6128plus this does not happen. No biggie as my original Multiface 2 works fine on the 464plus, and the Remake can be used to load, it just cannot be hidden. Most odd!!


Now to work out how to copy Anti Multiface accross and make the first Speccy-port-cart-port CPR file. I am going with Uridium, because it all loads into 64k so will work with AntiMultiface and hopefully then make a workable GX cart.


Wish me luck

Interresting...
On the original MF2 what is the eprom version ? is it 8B ?

Both devices should be similar... may be there are other differencies between your "Regular" cpc+ and your "Extra" 464+
Title: Re: MultiFace II clone
Post by: CraigsBar on 10:39, 30 April 15
The eprom in my real plus mf2 is 78. I swapped the eproms and it made no difference. Like I said no biggie.

The big issue now will be to get antimultiface working so I can try some more gx conversions.

I might remove my acid inside board from the 464 plus. Does anyone have a spare plus cart slot riser?

Interresting...
On the original MF2 what is the eprom version ? is it 8B ?

Both devices should be similar... may be there are other differencies between your "Regular" cpc+ and your "Extra" 464+

There's nothing extra on Craigs 464+ that would break compatibility with the MF2, it just has the extra 64K and the floppy circuitry added, so essentially it's a standard 6128+.

@Craig: I'm pretty sure I included a disable jumper on the ACID inside PCB. You just need to move this jumper to revert to the original state.

I'll take a look next time I have the 464 in pieces.

Yup, the jumper is there. This is your PCB: http://www.cpcwiki.eu/index.php/File:AcidInside1.png (http://www.cpcwiki.eu/index.php/File:AcidInside1.png)

You could even add an external switch instead of the jumper if you want /need to switch it regularly.

I'm doubting about the GALs...  and may be the LS670 or LS365 but i find hardto believe that all LS are bad....

Well... does everybody knows about incompatibility issues between GAL16V8D-15LP and GAL16V8B-10LP (which were the ones in the first batch)
Also do you have any idea to test a 74LS670 ?

GAL16V8D-15LP are just slower than GAL16V8B-10LP, it may be a problem.
Do you still have one card from the 1st batch ? If so just swap the component on socket from batch 1 to batch 2 and check who is not working.
Also double check that you did put the right GAL on the right socket.
For the smd ones, no easy solution.

I don't know for the speed since J.Leandro says wrote in the file he tested successfully with a 16V8-25LP
Well i asked someone who bought it in France (post is faster), i'm waiting for the answer ... May be if he lends me a MF2 clone for 1-2 weeks ;-) it will be great.

No,
in fact the problem is the supplier sent me 470Kohms instead of 470Ohms SMDs.

It is common to find it in the 35€/70€ range. (I bought mine for less, 2 years ago)
By the way, the MX4 version is new, so probably more reliable.

Not to mention that the GAL used in the Multiface repro (or the PAL in the original design) are specified for 20 years data retention. After that, one day, they will be gone.
Title: Re: MultiFace II clone
Post by: Bryce on 20:54, 17 June 15
I wouldn't pay any attention to those specs. They are absolute minimum lifespans to cover their ass. In reality they will most likely still be ok after 50 years.

I have one of the very first flash chips that came out. I got it around 1988/9 and recorded some data on it. I can still read the data today and it's never been re-written.

Correct. EPROMs hold their data much longer than flash. I have EPROMs from the 70's that still work fine. Eitherway, he was talking about PALs which are neither flash nor EPROM. The point I was making is that manufacturers state the minimum life expectancy so if they say 20 years, the part could still easily work fine for 50 years or more.

Hi there,
Yes indeed Talrek did a great job!


I found today that the MFII doesn't work with the Firmware 3.15, anyone else got the same result? I assume the original MFII would do the same, I didn't dig it out to check however.
Title: Re: MultiFace II clone
Post by: CraigsBar on 15:56, 21 June 15
Mine works fine with fw 3.15. So long as I use the correct ROM for either plus amsdos or old gen amsdos/parados
Title: Re: MultiFace II clone
Post by: dxs on 16:11, 21 June 15
Ok I'll look into it, strange because it works perfectly with the X-Mem and internal CPC firmware (or alone on the expansion bus), but crashes the cpc as soon as the button is pused when FW3.15 is enabled.
Title: Re: MultiFace II clone
Post by: CraigsBar on 16:22, 21 June 15
Hmm, on a mother4x? How is it powered?
Title: Re: MultiFace II clone
Post by: dxs on 17:24, 21 June 15
I tried both external PSU and no external PSU, same result. Anyway this is just the X-Mem and MFII. Same result on my 6128+: MFII works fine except when FW3.15 is enabled. Symptoms are: when the MF2 button is pressed, CPC freezes (nothing else happens).
I don't see it being PSU related. If I boot on the FW3.15, then (while CPC is running) switch the X-Mem switch to Internal Firmware, then the Mf2 works fine. So I thinks it crashes when it tries to access the 3.15 firmware on the X-Mem...


The MX4 can be ruled out also, as I tried with an edge connector ---> double 50 pin female cable and the result is the same.


Btw I have 0E firmware in the MFII, what is yours? (pop up the Mf2 menu, then press f0 it should display checksum).
Title: Re: MultiFace II clone
Post by: CraigsBar on 21:34, 21 June 15
If you have a plus, have you tried with a FW 3.15 cartridge?


I no longer use the XMEM on my plus. I found it behaved wierdly and be VERY temperamental to power supplies.


I did get it stable using a PC Power supply for everything, the Mother4x, Plus, and external floppy drive / hxc.


However since I find the Symbiface II just works with any powersupply and offers more functionality (RTC and PS/2 mouse) then I have swapped back.


I still have the Mother4x attached, and have the MF2 remake, Playcity and MiniBooster in it.


The 464Plus, Symbiface II and Mother4x are all powered from the PCPower supply.
The HxC / and external floppy drive are both powered from the Monitor supply.


So far not a single crash lockup or failled boot. I am happy as larry LOL


I no longer have lower rom support on the expansion, but as I have a c4cpc I can use FW 3.15 as a CPR in that.


ROMAN 1.0 is a symbiface II rom manager tool and with the FW 3.15 expansion rom in slot 1 of the Symbiface II the Silicon Disc etc all work as they did with the xmem.


Craig
Title: Re: MultiFace II clone
Post by: dxs on 23:07, 21 June 15
Good point, I'll try with the fw3.15 CPR and report back.
Title: Re: MultiFace II clone
Post by: gerald on 08:49, 22 June 15
XMEM in boot mode and multiface II replace the internal lower ROM. Using both at the same time = ROM clash.
It is the same issue as replacing the internal AMSDOS with an external one.
Title: Re: MultiFace II clone
Post by: CraigsBar on 08:51, 22 June 15
That would explain it then.... Use a fw 3.15 cart instead and switch the xmem lower ROM off.
Title: Re: MultiFace II clone
Post by: dxs on 11:44, 22 June 15
Hi Gerald, Hi CraigsBar,
Actually I was thinking about something along those lines, but not having looked into it deeper I didn't know if there was a local disable line on the X-Mem regarding the Lower ROM.
So everything should be working fine with the cart then.

I paid a bit extra and purchased it like this, forward thinking  ;)

Thanks to @talrek (http://www.cpcwiki.eu/forum/index.php?action=profile;u=1195) I now have a Modified MF II with a toggle switch to flick between CPC Classic/ParaDOS and Amstrad Plus versions of the Eprom.


I made a little adaptor out of a spare Eprom socket I had lying around. So the mod is completely reversible (Remove the Adaptor and reinsert the original Eprom.


The only change I needed to make was a little trimming of the Socket on the PCB to make way for the switch underneath the new Socket adaptor and the new Dual Eprom. See the photos below if this is not clear.

Hey Guys'n'Gals,

By accident I found the Source Code of the Multiface II. So enjoy the weekend and have a look on it. It's on the attached DSK[nb]Oh shit! I can't attach DSKs!!![/nb]. Ok, all again... its on the attached ZIPed DSK file.

The DSK is in Vortex Format, so you can read it with any 80 Track DS drive and a good DOS like X-DDOS, VaraDOS or VDOS.

On the DSK you will find a lot of stuff which is not in public yet, so have fun!  :)

Hmmm, 27C128 are getting rarer these days. I could possibly spare 1 or 2 from my stock, but that's about it. If you can use 27C512 instead I can probably spare 50 or 60 of them :)

Edit: I just had a count up of my Immediately accessible straws... 10 straws, each with 13 eproms, and 1 Straw of 11. OK Not hundreds, *just* 141.


All Brand spanking new AMD 27c128 chips never programmed and ready to go.

With "getting rarer" I meant that the normal suppliers don't stock them anymore. Most IC suppliers used to start at 27C128, but now the smallest them seem to sell is 27C512.
If you've got that many, then sell some to Talrek. :)

I'd give them to any of the hardware guys here. Just keep one straw for myself. So if anyone needs any 27c128's just let me know

Is the source code this one: ???

http://www.cpctech.org.uk/docs/multface.asm (http://www.cpctech.org.uk/docs/multface.asm)


This comment somehow really pisses me off. Since month we all try to get this damn source to make a ROM which runs FOR CPC6128 AND 6128 PLUS.
I did know there is source but couldn't find it all the time. After getting to MUC I found it and posted it here. Now you come up with the source. So you had it all the time and didn't share or what?


If you want to know if it is the same source then COMPARE IT BY YOURSELF.

@TFM (http://www.cpcwiki.eu/forum/index.php?action=profile;u=179): I did not intend to piss you off.

The source I posted is a dissassembled I made in 1996. It can't be re-assembled without many changes and it's only partially commented.

I had it on my original Amstrad webpages.

I didn't know you were looking for this source, I thought you had access to the real original sources which could be re-assembled easily.

Un milagro sería si yo hablo alguna vez decente español.  :laugh:


BTW: What's a good Spanish translation for "Disc full". Maybe "Disco lleno"   ?? ?? ?? ?? ?
