Wow! Crazy board with the manual air-wires and diodes. The even crazier thing is that your board has the same manual hand-soldered wires and diodes! These must be pretty low-volume stuff for IBM to have bothered with that (and not just had a new board made).
As far as I can see it has the same pinout as the other 3178 controller, so you should be home and hosed with the little adapter board.
Do you want to build it yourself or go on the group buy? Let me know either way—these boards look cool, I wish I had one!
