    Another newbie question, but what is CP/M? I know it is an operating system, but what are its origins? -Joe

          LOL. It was what was hip before MS/PC-DOS, at least
          that can be said. Generally ran on 8085's or Z80
          chips. The 8088 is what was used in the IBM PC. It had
          2 modes of operation - MIN and MAX. It was set shortly
          after power on. In MINimum mode, it was essentially an
          8085, with 64k of ram I guess. There was also
          something called cp/m-86, which was...you guessed it,
          cp/m for 8088/86's.
          I spoke to a dame the other day. She asked me a
          peculiar question. It was kind of a sketchy thing, but
          she wanted help remembering "a program" that was sort
          of hanging out there in those days, and supposedly
          Olivetti commandeered it or something - kind of what
          Stallman and Torvalds wanted to avoid when they
          created/adopted the GPL. She was like "was it
          cp/m...dur, don't really know". I couldn't make heads
          or tails of what she was getting at really, but I
          thought I'd pose the question to the group. She used
          to deal with ALOT of technology in her job, working
          for school districts I think and whatnot. I know it
          wasn't cp/m - that was a product of Digital Research.
          Anyone have any clues?
