Hap- no I didn't scan it, and it doesn't look like I shot video. I've got the case here, but I sent the PCB to Kevin. The on/off button was not on the matrix, and the tuning cap was internal. It looks like I left button matrix column 5 (PE0) off my text file, and I don't see in my notes which port A pins those other 2 buttons are connected to.

I got Little Professor '82 today. Looks just like the pics on Datamath.

I'm going to be tied up with work for a couple of weeks. I've decapped, photographed, whinked, and re-photographed a bunch of chips that I need to composite and dump the ROMs/PLAs from. I've also started electronically dumping SM510/511s, and built a circuit to energize one LCD segment at a time.
