Before having applied power, you might have wanted to

voltage conversion tanks for clues to the supply in and outputs before
applying power in any way. It might just be that Molex had cheap connectors
that week, and you fried the thing completely (sorry to be down, but it is a
common connector)
Not likely that I fried it. It goes through the motions of working: motor
spins, head-load solenoid tries to engage. Stepper steps (although a bit
haltingly).
This unit is WAY too recent to be a three-voltage drive. It's the most
contemporary 8" drive design I've ever seen, in fact. That's why I
thought it was at least plausible that it ran on 12V!
I'm going to go for it and try a higher voltage. There's no reason that a
12V regulator would be hung off the input - through a 100-ohm, 5W resistor
- unless there was supposed to be > 12V applied.
