For the record, at had a *Motorola 68k* release sold to customers using the VME/10, MVME rack mounts, that sort of thing, so if upstream 3B2 source provisions don't have VMEbus support, that could possibly be transplanted from a 68K System V distribution.  There is one on bitsavers afaik, not somewhere I can look at present.

Also count me jealous as all get out, I've been hunting a 321SB or 321EB for years, luckily landed two MAC-Tutors and a box of MAC-8 and MAC-4 chips in my search, as well as a 32000, 32001, 32006, and DSP32, but none of the WE32 eval/dev boards.  Anywho, this is an area of particular interest to me so happy to connect more off list regarding this one.
