Do a web search on "microcontroller" and "breadboard". Or read up on the Arduino. -- Tim Wescott Control systems, embedded software and circuit design I'm looking for work!

I will have to get it out to see more exactly, but the idea was to run the SDK-85 ROM code. The hard part was getting all the right inputs to the 80C85 Vcc or ground so it would run.

It all depends on how you define "computer". Cheers, Eric

For penance you are required to code FFT in COBOL and enter it with an 026.
