Nice writeup! Whether or not anyone unearths the sources that will serve well as a reference.
FWIW, Bill Greathouse had decompiled most of TM2 about 20 years ago in order to fix some bugs (TM2 was written in itself and is mostly M-Code to be executed by a runtime). I could never get his attention long enough to find out exactly how he did it or get ahold of any of the tools used.
I have a bug-fixed version of the compiler (both 64180 and Z80 versions) somewhere and will try to get it unarchived.
