Long lost Econet packet tracer, these sources were recreated from versions 000-0124 and 000-0131 recovered from an ST506 (!) hard drive.
They build to the same size binary as 13-Dec-1988 version, with some minor binary differences:
* Push/Pull macros use LDR/STR instead of LDM/STM
* ADR encoding with Objasm differs to AAsm
* MOV immediate no longer has reserved bits set
Built, but not tested.
