rarest computers

I just thought of a couple of uncommon machines I have...

A DataRAM 22-bit Qbus enclosure with a real DEC CPU, and a bunch of 3rd-party
boards including RAM, a watchdog card, a Dilog DQ614, and a card that
emulates an RXV21, but plugs into a more "normal" Tandon TM848 8" drive.

A Perkin-Elmer UNIX System III workstation - it's odd because it uses a
pair of MC68000s to do page faulting (rather than some magic wad of TTL
or a later processor like the MC68010 that saves enough state to do virtual
memory in software).

There's nothing horribly rare about a Q22 enclosure, but I don't recall
running across too many non-DEC boxes (besides Heath). It's an interesting
mix of mini and micro technology from the early 1980s.
