Got it, thanks! I updated my converter program to match. I found 2 bits in TI Programmer that were obscured by dirt: $3CB from $81 to $A1 and $3EF from $03 to $13.
I decapped the Amaze-A-Tron TMS1100 but the top metal layer is pretty dirty, so I'm going to try to clean it in H2SO4 to get a nicer pic before using Whink to remove the metal.
