Pff, a microscope =) Makes me think... hypothetically is it possible to show the connections when viewed under xray?
Good luck redoing the Konamis
Rik can you make a photo of the Fab Fred PCB? Tandy-12 MCU has label CD7282SL (it's a TMS1100) *edit* hmm, Tandy-12 has 12 buttons, Fabulous Fred has 9. Not equal then.
