Hi Tim:
Pretty sure that I've got a 3.5" floppy, dual-drive data cable and dual-drive power cable here for you, you didn't specify
720K or 1.44M but may have both in a box.
IIRC, also have a couple 5-1/4" floppy drives in 360K & 1.2M sizes with cables, too.
I do have a tower PC available with all 4 floppy drive sizes in it, that can run any 2 floppys at a time, specifically for
reading old floppy disks to a hard drive for data recovery if anyone has a need for that, an oldie but a goodie keeper.
I'd have to look but might also still have a copy of the program COCO2PC which will read floppy disks from the
Radio Shack CoCo Color Computer disk format to the standard PC floppy format.
