Ok all you ex-aerospace contractor types out there, here is a challenge for you. My new VAX came from an Aerospace contractor and had a Q-bus board in it business. according to Hoovers.com) The board is dual width Q-bus marked "K Systems" "AITG" "Rev C" On board it has a Z80B, Z80BPIO, AM9513 (floating point?) MK6116 (2K RAM), 2764 EPROM marked 35112A0B (c) 1993 KSI, and a part marked MK4501N-12 (what ever that is). Then it has a bunch of analog circuitry, four rotatable switches (set to 0,0,0,0), 7 thinline coaxial connectors, an LED, a 20 pin (10 x 2) connector, standard Q-bus decode logic with what looks like a bunch of dip switches to set the CSR and what looks like a temperature compenstated and potted crystal oscillator. I'm guessing its some sort of time base generator. I'm sure 'sho dev' won't know what the heck it is ! :-) --Chuck
