I don’t know if Jon Newton is in this group, but he pointed me to this t-shirt that may be of interest.

>>  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.
