      The case is in rough shape:


      ...but you're right - it's a bargain. I'm going to have to read up on
      re-forming electrolytic caps. Here's some other info he sent me:

      "The boards are:
      - Cromenco Z80 CPU board
      - Scitronics real-time clock board
      -- The BIOS I wrote for CP/M makes use of the clock but I'll be darned if
      I remember how!
      -- Probably needs a new battery
      - A serial/parallel board
      - A serial board that I made (wire-wrapped). It used the 8250 UART which
      used by the original IBM PC at that time. A write-up of the board's design
      can be found in the June 1984 of
      Microsystems (Sol Libes magazine).
      - The Morrow Disk Jockey 2D/B.
      --The BIOS was modified so that an 8" double density floppy could hold
      about 1200KB instead of the standard 800 or 900 KB. When my friend and I
      made the change all the nerds that were our friends were amazed and
      proclaimed that it was all the storage anybody would ever need. Times have
      changed, right!"
