So I had a real ModelA/III master and I was looking at the sectors and noticed there was a MODELB/III and MODELC/III deleted on the disk. I checked and they were still recoverable/undeletable even thought it was a TRSDOS diskette. I also noticed something else, all the ModelA/III sectors were using directory DAMs and not STD DAMs.
Did a quick check of the sectors of each file and they look similar, I haven't tried them on a 4P (I know you can press A-I think G) to boot alternate Model III roms.
