Awesome! Tell us more details please.

That looks amazing. To me it looks like it is practically Amstrad clone packaged to ITX sized MB and it seems to have ST Microeletronics Z80A on it. Brilliant!

Installing that to some beautiful ITX case would be seriously cool on anyone’s desktop.

Pre-Order-List?

Totally awesome!!! What is the additional cost if 8 or 16 Mx4 slots were present?

Duke M4 card added, Just CPC 4 is Wi fi ready

Details ?
- base board is in THT, so self assembly is not really hard.
-PS2CPC from Gerald , PS2 keyboard interface is on board , thanks

-ROM and basic CPC 6128 1.1
-64 kb ram-board size 17x17 cm as ITX (mounting holes can not fit )- 7 slot for expansion cards , Mother X style. ( Playcity, M4, or others)
- Bluetooth module for load CDT files from mobile phone , for example "Breaking Baud"

On the moment i have also 512kb ram expansion card, 4mb ram expansion card, Floppy interface card also in Mother X style .

- Changes from prototype...
- i cancel ATX power supply connector, now board have normal 5,5/2.1 , 5 volt socket power supply . Power on/off is still as in PC. Push button

And yes, i know, you kidding me.

How do you do the Gate Array. FPGA? Can you point me to the FPGA code please, I am building clone of Russian and Eastern Germany home computer, I can integrate your code. Right now, I have Robotron. I call it "The Red Kremlin".

Get in touch if you want to do business with me, but I need your code and schematics first. I can distribute your product in USA.

He use the Amstrad schematics and spare IC that are Amstrad Copyright and resell them to do retro-business. $:-\$

Sure, then he must have permission from Amstrad / Sky to call it "CPC" and use their chips and schematics, right?
Like the "Spectrum Next" guys who got permission from Sinclair - Amstrad - Sky to do so.

The problem is the limited GA qty (NOS or used) to do a real "CPC next" w/o FPGA engineering making that design not viable IMHO.

One thing is damn sure - I wouldn't wanna disassemble my CPC just to stick the GA on some ATX motherboard. Like the idea but you need to get GA into FPGA, otherwise it is a no starter. Check out what Spectrum Next guys were doing. How come the CPC community has no FPGA model of the main chip of their machine. What have you guys been doing all these years. Just playing games?

BUT OVERALL - GREAT PRODUCT AND ACHIEVEMENT!
CONGRATS

Also, there are several FPGA implementations of the CPC, for example on the ZX-Uno.
