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
