Sean do you have a list of interesting TMSxxx decap subjects? I'd like to do some nominations. smile

MB Dark Tower(though I know you are already looking for one) - definitely TMS1400
MB Super Simon - likely TMS1100
TI Little Professor - says TMS0975
TI DataMan - says TMC1982, I wonder, maybe a TMS0980 derivative?
TI-45 - says TMC1983, not as interesting, just that it has this 198x MCU too.

I also wonder, who were the first customers for TI TMSxxx. Currently the oldest ones we have are from 1977: MB Comp IV (serial 904) and Parker Bros Codename Sector(serial 905)
