That's probably it. The drive is not stuck, so I'll put it on the MFM 
tester later this week and see what's up. Does the adapter board have 
its' own power supply?

I'm guessing it's a Shugart SA1000 to MFM interface card. On the bottom 
side of it it says "Perq systems", that, the little stack of washers to 
offset it from the drive, and the numerous wire hacks on the board mark 
it as yet another product from the mighty Three Rivers company :-)

God my shed is getting full....
