When I had a problem with the BOB I made a three wire cable to run from the parallel port to the stepper driver to eliminate the BOB as the problem. Could be you wrecked the parallel port. I would not think you trashed the stepper or the driver. but maybe a dead short across two pins would knock out the port

No, it's definitely the driver. Good note on the parallel port, though- that seems like it could be an incredibly painful problem to track down.
For what it's worth, I got some Gecko drives to replace the exploded one (plus the unexploded ones on the same board). The parallel port and steppers seem fine (no shorts on the stepper, and the parallel port seems to still function).

Glad to hear you have it sorted out. Good choice on the Geckos
