I've also seen an i486 on a dual-height Qbus card, but it was definitely
not for the general purpose market... it was in CompuServe's X.25 boxes
as a replacement (up/down-grade?) for a PDP-11 processor. In the last
Qbus incarnation of these systems, they put 3 9-slot Qbus backplanes in
one (big) rackmount enclosure, along with 3 power supplies, 3 halt buttons,
3 run lights, and a wad of custom serial cards.
I have one of these enclosures at home, but no proprietary cards.
Someday, I plan on putting 3 independent systems in there, running 3
different OSes (RT-11, 2BSD, and one other, haven't decided what). I
might even be able to get away with putting 3.5" ST-506 drives inside
the case and running them off of the internal PSUs, presuming I don't
load these guys up with cards.
