That's a good idea. The original machine was basically a PROM, so add
some memory and a sequencer, et voila -- a real computer.
Is 'Science Fair' a name used by Radio
Shack/Tandy? It seemed to be that
in the UK - we had all sorts of 'Science Fair' kits, mostly of the '3
transistors joined by spring terminals' type.
Yes, that's the one -- king of the spring terminals.
There was also a Science Fair Microprocessor Trainer that I find much more
interesting, even if it's not mechanical: TMS1000, hex keypad, LEDs, and
speaker.
