I was looking for something else and ran across a two-binder set of something called "PC-MOS" by The Software Link, circa 1992. I opened the shrinkwrap on the nstallation manual and the thing looks like it's a multi-user version of MS-DOS, talking to terminals. I appear to have a 5 user version. Anyone familiar with this animal? The version is 4.2. Cheers, Chuck
