Copycat TMS1730 output PLA O1,O3,O5 are unused, so it's safe to assume that those are not bonded to any pins. The microinstructions PLA is same as Big Trak, sorted backwards (eg. bigtrak term 1 = copycat term 30, etc)
From the die pic, I assume that the number of pages in the ROM is the same as TMS1000. The page size was halved, 64bytes to 32bytes. How did you convert the raw ROM?
