[Coco] FD-502 drives anyone?

[Chad H]

Recently had issue with original Tandy FD-502 drive unit where sometimes it reads/writes fine...somtimes I/O errors.

I also have another 502 drive that I received in semi-working order... one side works just fine, the other not so good.

These are just bare drives now, removed and replaced with PC/XT 360k drives.  If anyone wants them let me know.  Maybe they just need cleaning or adjusting, I don't know.
