was later. Also Draft 10 became the foundation for IEEE854 which is Radix
Independent. IEEE754 only concerns is with binary floating point.

If I knew how, I would.

My first guess would be that it was an relocatable macro assembler/linker combo
that ran on a 6800 or 6809 Exorcisor system. One with those giant 8 inch
floppies. If a cross assembler and linker, then it was native MC6800 program. I
don't t hink it was an OS9 assembler/linker as the standard OS9 module header is
not a part of the assembler directives. Instead it is done with FDBs and FCBs.
