[Coco] Need help (of course)

[Arthur Flexser]

Bill, what I'd try is taping over pin 12 on the Drive 0 edge connector and
pin 10 on the Drive 1 connector.  The odd-numbered pins (all grounded)
should be on one surface and the even-numbered pins on the other.
Hopefully, there should be an identifier next to pin 1 on the circuit
board.  If that works, then you can consider whether to bother with a
neater and more durable solution.
