Greetings, I will go to the storage room to get the exact model numbers. Off hand I know I have the 316, Varian 620i (rackmount), 2 pdp 11-05, 2 Data General Nova 1200 (I think), 1 Computer Automation, and a HP 2114 (I think). These were all used to test and checkout old "Linc" tape, 10 channel magnetic tape units, from a company I worked for in the late 70 early 80's.
