On more recent systems (right up to P4) that support only a single floppy or two, I constructed an "interposer" in the floppy drive cable that involves a DC37F connector and bracket, with a DPDT toggle switch that switches the motor and drive select lines of either the A: or B: drive to the external connector. I've got lots of external drive boxes, all with DC37M-terminated cables. Just grab the drive you need, plug it in and throw the switch. Surprisingly, quite a number of later motherboards with floppy support do fine handling FM disks. --Chuck
