I picked up a 55sx recently and found out that the floppy drive is only useful as a bookend now. Maybe I'm completely wrong on my assumption, but after looking up some pinouts it seems I should be able to patch a cable and use a non ps/2 floppy so that I can use the reference disk when needed.
I tried this using a known good drive, using a straight cable with only a single connector for a drive. I cut only 3 & 6, as those power the drive and/or are unused/ground by a standard floppy. The rest of the odd pin grounds I left. This was based on my impression that this particular model didn't use a media sense drive.
The system boots normally and doesn't give a 601 error, but cannot use the drive. All I get is a "Drive not Ready" dos error. The motor spins and the head seems to try to step, but that's it. Has anyone else done this and can point out where I may have gone wrong?
