CP/M Utilities - Product Information

Oldies (But Goodies)

Commodore and CP/M
It is truely amazing how far the personal computer has evolved over the two decades
since its birth in the '70s.  One of the first true computer operating systems was called 'CP/M'.
Although CP/M has long since been pushed aside by DOS, Windows, Macs, OS/2, etc,
there are still a large number of collectors and enthusiasts who like to tinker
with these machines.  (Also long gone are the days when software was written
to work in a few kilobytes of RAM!) 
Although we no longer support our line of CP/M software (developed in the '80s),
we had collected a considerable amount of technical information on CP/M, in
particular the CP/M+ version used on the Commodore C-128. (remember that machine?)
This information is being made freely available, on the sole condition that
it is for your personal use and is not to be exploited commercially
(i.e. don't print off our files, bind them as a book and sell them!)
