Dave Sieg: It required a DEC KA-10 (5 tons of stuff that barely could do 1 MIP!) just to boot it!
Dave Dyer #1: Alas, I don't think the F1 ever had a proper console - it always had som KA-10 attached.
Dave Dyer #2: Superfoonly required a console computer to boot it up, load it's microcode, and so on. The original concept was to use a PDP-11, but the expedient thing turned out to be to use a KA-10 as the console computer (as an interim measure) and eventually to build a cheap pdp-10 out of 2901s and use it as the console computer.
