I almost finish  it. New PCB, old components in THT for easier self assembly. In this week i send  prototype PCB  to factory.   Is easier made it from buy somewhere  :D

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/


Bryce

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

Bryce.

Piotr

Thanks,  :D edge slot is for connector, like in my previous floppy for ZX Spectrum.

Looks nice !!


What did you produce the 3D renders with ? Kicad, Eagle ??

Piotr

Diptrace. Very easy and friendly software but free edition have limit up to 500 points.

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  ;)

Those Zx interfaces are +3 compatible or you have make another kind (Opus, Disciple..)??

on Photo is D+ clone. Yop ,edge connector 2x25 pin. Nothing is missing . PCB is  not fully routed. Echh not show unifinished project again  ;)

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

Well , but ZX +3 have FDC controller on board so why made externial floppy interface  :o

as said before : for those +2/A/B that may not... do they have FDC ?

Piotr

OK, 99,5 done  ;D Board is in PCB factory.

May be holes on corners should allow to fix it into a box or something like ?

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

Ok, prototype running ;) Now i fix some mistakes on PCB and send it to production.

DDI clone, amstrad cpc 464 floppy interface, first run - YouTube

And yes, Batman forever running on my 464 (ram upgrade)

Token

Very nice work Piotr. This is something I'll definitely buy.

dragon

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

Ok, something like this. Clone in enclosure. Estimated price 55 euro, be aviable in june.

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

Gryzor

Hm, that'd be interesting!
