Rounded floppy cables
« on: January 04, 2008, 01:21:43 PM »
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.

Thank you! Did you take the connector apart and recrimp it, or just cut the cable and re-connect the wires in the correct order?

Fair enough - I will try to do the same.

All you need is two cuts

What do you need to cut if you re-crimp the connector?

IIRC I included the GND lines on sides when doing the swap (so that the middle is wider).

Can you elaborate on this please? I don't understand what you mean.

Thanks again

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

Cheers guys.

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?

OK no worries. Doesn't seem like too big a job to take the connector apart and turn the twisted cables around.

Thanks again guys!

Are the wires inside a ribbon cable numbered consecutively? IOW can I just count from wire 1 to wire 10, then count from there to wire 16 to find the wires I have to reverse?

Never mind. I tried to take the connector apart and swap some of the wires, but it was so fiddly I lost my temper and the cable suffered a fate worse than death.

I'm going to get a PC floppy cable with the twist and crimp a male connector just after the twist, making a very short M-F floppy cable with a twist in it. This will then function as an adapter so a new, non-mutilated rounded floppy cable will work on the Amiga.

I would cut the wires and the solder them.

I think I would break the connector if I try to open it :roll:

That's what I did. Then I accidentally stripped some of the insulation from one of the wires while trying to remove some sticky backing which is supposed to keep it in place. Then it wouldn't go back in to the crimp connector properly. Then I lost my temper and threw it away :roll:

I'm trying to find a source for 34 way male IDC connectors to crimp on to a PC floppy cable to make a little adapter.
