Does anyone remember the "computer" from 70's made out of long plastic switches and wires and lights?
Yep. I had one. It came as a kit and I had to assemble it. The hardest part was the Ground wire, which looped past all the lightbulbs and more less around the box. The kit had one roll of insulated wire, so I had to get the insulation off wire for this. Edited - fixed some typos
As I remember each switch was basically 8 pairs of Break/Make (ie either the bottom wires was connect or the top wires) with 3 hoes for each and every connection. There were 10 switches and lights. This gave about 80 "gates" (ie you needed two to make an AND)
Nope, no leftovers of that in my attic. Only in the attic between my ears.
