There is a set of files on KIM,MUS which allow for the assembling of code
for 8080, 6800, and 6500 type micro processors. Vague documentation is to
be found in SYMBOL.TXT[KIM,MUS]. The program to run is SYMBOL.DMP[KIM,MUS].
This is a full fledged SAIL program, not a set of FAIL macros. You can try
asking RP questions about it, but he doesn't know that much about it.
