If you connect an external drive to a STFM, if you pay attention, you will notice that the internal drive spins up if you access the external one and vice versa
Lando_C wrote:Pin 5 you say, Ijor ? that makes sense, the STF would not need an external drive A, but you would want the external drive to work without needing to re-strap it or special cable for stf models.

OK, so I have the pins 0-9,11,13,15 and 17-34 straight onto the floppy cable.
cable 10 and 16 from the floppy (both motor on signals) to hole 16 in the motherboard.
cable 12 from the floppy to pin 6 on the external floppy port (drive select 1)
cable 14 from the floppy to hole 10 in the motherboard (drive select 0)
This doesnt work right, The computer never sees floppy B (beyond the twist), reads disks fine as logn as floppy B is empty, but bombs out if both drives have disks in them.
with cabel 12 to pin 5 as suggested by Ijor, th computer finds two floppy drives, but reads from them both when you access the B icon and only from A when you access the A icon. And drive B light stays on all the time.
