Happy to help. I'd just ask that you share whatever you turn this into, so the next guy can find it, and on and on....

Besides, anything that makes it practical to disassemble LEX files on a PC would be a nice thing to have.

In the LIF disk project, look for a text file called NMEM2 (e.g. on SWAP/CHHU01), which is a listing of the Saturn instruction set mnemonics with decimal and hex values, made by John Baker in 1984. The notes I have on a handwritten copy say:

1. For field select options, I substituted 0 for 0 - 7 and 8 for 8 - F
2. For jump distances, I used zeros
