I started collecting calculators & old computer equipment, but quickly ran out of space. Darn!
I do wish I hadn't thrown out all my old punch cards, though.
WOW, I bet between us we have quite a collection. My oldest "computer" (trainer) is a Minivac 6010. I also have a PDP-8 with an ASR-33 Teletype.
My more "modern" ones are on the par with my Imsai 8080.
