I'm not sure if this can only run on the HP-71 using one of the Debug LEX files. I have the Debugger LEX files on 5-1/4" or 3-1/2" floppy disks (also compliments of TSA). But, I'm sure that JFG already has a copy of this disk image.

Yes, the Debugger s/w is a set of LEX files that only runs on the 71B with the Forth ROM installed, sort-of layered over the HC ROM and LEX files in the SC ROM. The 71B Forth/Assembler tools work, but are slow and quite limited by the available RAM, which is what lead to the creation of the areuh tools, originally built on UNIX. I'm fairly sure all the internal HP tools used to build the 71 and ROMs were also UNIX-based and I don't recall them ever leaking out into the wild.
