Will a rounded floppy cable work with an Amiga 4000 floppy drive? I know the connectors will fit but I'm just not sure if the cables are wired up the same.


Ive just done it for my A4KT (It runs straight over the top of the CPU card so the round cables really are a must.
The board connector and the first connector was wired one to one so no problem there, the only thing is the lead I got was to short so I had to fix the last connector, I took the two top clamps off (one to hold a pull tab), both lost at least one tab so I glued it back on. :D
the rewiring was easy, the cable end was what seemed to be laminated with some plastic to keep it spaced, I removed the plastic cover from the pins I wanted to move over and then moved the wires over, tested it with the multimeter and plugged it in.

Worked first go :D

Oh and as for rewiring it, round cables seem to use multi coloured cabled so its as easy as match the wire colours.

So just to clarify, the floppy cable (for an Amiga) should be connected straight through on all pins - right?


Correct (Thats what I did)
there is a jumper on the board to set the drive to the first or second drive where as PC drives twist the cable to signal the difference.

Couldn't I just leave the cable as is and then set the drive to DF1, and let the twist in the cable switch it back to DF0? Or is the twist not compatible with the Amiga?


Nope, sorry. The Amiga expects a flat cable, I dont know if there is a floppy select on the Amiga cable vs the PC one or what but crossing it over simply doesnt work.
