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.
