   I built a prgrammer for the Osborne 1. It had a 8255 for the supposed   
   Centronics printer port but being CP/M you could do all sorts of strange   
   things with it. Obsorne officially supported using it as a GPIB port.   
      
   Computers were a lot more fun when you could directly mess with the   
   hardware. The 4 voltage (+5, -5, +12, +26) 2708 would require a little   
   more work.
