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. -ethan -- Ethan Dicks, A-130-S Current South Pole Weather at 03-Aug-2004 02:50 Z South Pole Station PSC 468 Box 400 Temp -77 F (-60.6 C) Windchill -117.3 F (-83 C) APO AP 96598 Wind 12.4 kts Grid 030 Barometer 668.9 mb (11046. ft) Ethan.Dicks(a)amanda.spole.gov http://penguincentral.com/penguincentral.html
