There's a PL/M80 compiler written in FORTRAN IV on the Walnut Creek CP/M CDROM. I've used it under VMS and spit the source through Microsoft's F80 (it took a little tweaking and the resulting object files were so large there was no point in attempting to link them). Gene Buckle has a copy of the CDROM hanging off his CP/M page at http://deltasoft.fife.wa.us./cpm/. Take a look at http://deltasoft.fife.wa.us./cpm/cdrom/CPM/MISC/PLM80.ARK in particular.
