there is a stack of them in my pile-o-stuff that need reading.
Well, if I look over my shoulder at the table sitting next to me,
there's an IBM 5170 (PC AT)-type case with three drives in it--a 3.5"
HD, a 5.25" HD and a 5.25" DD (1.44M, 1.2M, 360K in common parlance).
They're all on a single 34-conductor cable hooked to the floppy side
of a DTC 3280 SCSI controller. It's possible to set the jumpers for
4 floppy drives on the same cable as well, although you don't get
individual motor control that way.
