So a little while ago my IBM PS/2 4869 External 5.25 Floppy Drive "died". I was never sure as to why (either the MCA adapter card, the drive, or somewhere in-between).
I had some time recently, so I did some digging with it on my IBM PC 5150. I opened up the case of the 4869, connected one of the 5150's internal card-edge connectors to it and it worked! I checked the 4869's power supply, and it's working fine.
This means it must be that big, thick, honking DB37 cable that has a loose connection somewhere in it. So I'm probably going to have to build a new cable for it.
Does anyone know the pinout for the DB37 external floppy so I can build a DB37-to-17pin card edge connector adapter?
Or does anyone have any other thoughts or tips about this?
I've tried googling it and can only get bits and pieces of info, but nothing definitive.
Thanks!
