Hold it... plugging the drive in backwards is a real no-no because you cross
the power supply connections in a major way. But...

I have plugged and unplugged Disk ]['s from both the original controller card
and from the IIGS disk port while the power was on... many times and never once
did I fry the motherboard.

I did plug the drive in off center once -- that blew out the LS125 in the drive
and the LS174 on the controller, but nothing happened to the ][+ the card was
in at the time.
