That's what you get for jimmying the cover interlock :)
The ZIF slots, "no cables attached to the cards" and the "identical POST
pass/fail LEDs on every card" features of BI are nice for working on, but it's a
real problem for restoration. Anything that attached to some peripheral (DEBNT, KLESI-B,
KDB50, DMB32, etc) required a special "transition header" that adapted the
backplane to the cable set for that particular device. Spare BI cards are fairly easy to
come by, but everybody has thrown away the transition headers and the cards are pretty
much useless without them.
