The Trailing Edge's OS Quick Reference


Updated 12/27/98

This a a quick ref for several older operating systems. The original source was the OS reference sheets from the June 1983 issue of MICRO magazine. I'm adding other OS refs from manuals, books and magazines I have in the library. Hopefully this will help out someone as many older machines are found without manuals. I have most of the more common operating systems, if you know the commands for a less common OS I can add to the ref, please email me.
