external floppy drives.
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.
