PL/M & CP/M

Recently in my wanderings on the web I saw a comment(I don't remember where) that said at least one of the PLM-80 compilers floating around was built from a dis-assembly of another one. Does this ring a bell with anyone? Would anyone know where I might find these sources? I have the Fortran

Re: The TRS-80 Journey Continues

Another question for the masters here. I just tried to revive my Model III. More than half the keys don't work anymore. What is the conventional wisdom on cleaning these old TRS-80 keyboards? Is compressed air usually enough? Can I spray the switches with something like DeOxit safely? I

So, the bad news is no way found so far to make bootable floppies. Maybe not bad news as it gives me another fun project to work on. Further good news, however, is that I have revived my M3SE, MISE and 2 FreHD's so I now have hard disks for pretty much all my old systems. Just have to build
