But I think nobody uses cmos.

is it wire to wire?
The goal is not to disassemble my DDI-1 but just to change the cable.
I saw on a forum that it was necessary to cut tracks on the tablecloth...

Isn't this a reasonably well known issue with CMOS Z80s ( I think I've seen speculation that, since the instruction was unintended, it's just a result of how internal signals value when floating differs between NMOS/CMOS)
There's also a slight difference in LD A,R/LD A,I behaviour according to @arnoldemu

OUT (c),0 working 
but like OUT (c),255 
OUT &BC00,15: OUT &BD00,15: rem CURSOR REGISTER
?INP(&BFFF)

CALL &BFFC, &e9dd ,&c9 , &71ED, &BD00, &100
REM JP(IX) RET OUT(c),0 LD BC,&BD00
? INP(&BFFF)
255
Dear Zilog, does 1 CY really save you?
But SymbOS working

Last post by robcfg - Today at 18:47Isn't the DDI-1 wired to supply 5v on the floppy cable?
Could that damage the CPC?

Bryce.
Thank you for the link
I already had it.
so it's wire to wire wiring?
Thanks

Technical support - Hardware related / cable DDI-1 for CPC 6128
Last post by willow3411 - Today at 18:02Hello everyone,
So here I am going to try to be clear in my explanations.
I have a Schneider DDI-1 (external reader) with its Amsdos interface for my CPC 464. Everything works perfectly.
I would like to make a cable that directly connects my DDI-1 to my CPC 6128 (EDGE port).
Just by replacing the AMSDOS interface.
of course I would like to keep my internal 3" drive in A and the external one in B
I have the 34p cable, the 34p female connector and the EDGE connector.
The problem is that I don't know the exact pinout. I read a little bit of everything.
If anyone has a diagram that would be great.
Thanks for reading me.
