This is awesome! Will there be some spare boards available?


Did you know that Bryce is designing the DDI-2 with some extra features? Looks about the same size http://www.cpcwiki.eu/forum/amstrad-cpc-hardware/the-ddi-2/

Very neat layout. Don't forget to add the keyway (slit) on the edge connector.

Do you plan to use a edge connector to connect your clone to the CPC ?
If so you're missing a path through connector or you will have a real clone of the DDI1 with its major default  ;)

A fact about the CPC interface is that is almost the same as the ZX+3 one :) when you finish the CPC, you may consider porting it to the ZX so would be a direct plugin for +2A/B with no ROM need

It is only prototype . I draw this board from poor quality schematic so probably is few mistakes. When i run prototype  i redesign board for enclosure , thru board on top for connect other extensions and few other things.   Something like divide plus what i also made.

If you write "99.5% done, board into the PCB factory"... I may understand that is finished.

On the +2A/B manual was promised an oficial interface like the CPC's DDI, but never released...

On the "back 2 the +3" project, fitting a +3 cloned fdc controller to the +2A enabled floppy features on the ROM. Also a SED replacement was developed for this proyect with 6 ttl chips

Ohh, I always like buy a ddi from my poor 464.

So now we have the posibiliy to buy a ddi clone and ram expansion very cool|

Maybe in the future, you could join forces and integrate the 2 things on one motherboard a 464 upgrade kitt.

Great work!!!  8)
If you plane to reduce the electronic into a CPLD, I can give you the MX4 format size.
So, your board should be used by 464 users who already own it. :)
PM me if you are interested. It's free.  :P

If you were to turn the box 90 degrees, you could fit the drive as well, if you used a larger box.
