Does anyone remember how this is done? Or the BC11- to the one used in 8s?
Thanks, Paul

I seem to recall that the M920 has two boards with the
double-wide DEC connectors, that had a plastic spacer
riveted between them, and about 6" of the special DEC ribbon
cable soldered to each board.

Yes, and there is a variation on that (M9201???) that has taller boards and 6 feet or so
of that cable zigzag-folded in between. That is used every so many boxes to keep the
reflections under control. See the Unibus handbook.

Yes, that is the M9202.
I remember there being a hack to convert M920 from an 11 to a M935 for an 8.
