Anyone else have one of these "Microcomputer Trainer" things in the 80s? You could customize the pin-outs by attaching wires to the springs, and program the tiny CPU to light up the one-digit LED display or buzz or whatever. Was kinda fun, though I could do more with the Atari 8-bit machines of the day. :D
