SOLID STATE - DEC COMPUTER LAB with the pdp-8 I toggles... not RARE but is cool! RELAY - - MINIVAC 601 COMPUTERS for tube computer - - our sage stuff also. for solid state - some of our GE Erma material. for mechanical analog computer -- some kid of weird thing with gears shafts , bellows and I think this weird thing runs off compressed air. details pending for electronic analog computer - Syston Donner with Tubes in it not that RARE but we are proud of it! for calculators - W.W.
