Hap- Cool! I guess the Microcomputer Trainer instruction PLA is standard? I compared it to the one in Entex Basketball 2 and they are not identical, but I haven't checked yet to see if the instructions are just in a different order.

<edit>I finished checking the instruction PLA and all the opcodes are the same, but in a different order.</edit>

He does not want any credit, thanks.

Rik- Other "MSL" labeled TMS1100s I've seen are Rev B and the ROMs and output PLAs can be dumped. If it is a Rev E die, I have been able to use Kevin's method of executing each byte to determine high bits, but there will be some false positives that we will have to identify. I have not been able to dump output PLAs from Rev E dies, but we can probably figure that out.
