While everyone here is thinking of younger daze..

Did anyone else here ever encounter the cardboard slide-rule thingie that emulated a microcoded CPU, with assistance from the student (me) with a pencil and rubber eraser?

It was called a XXX-Bug, where I cannot remember what XXX was.. something like "Mik" or "JIT" or something.

I credit that amazing device with helping me understand how things really work under the hood, back in high-school. Up until then, I was going to be an electronics hacker (kinda like Patrick)..
