Description

This is an unassembled kit and requires soldering.  All components are through-hole.

With this motherboard, you can connect up to 6 expansion boards to your PAL-1 at the same time.  The motherboard also provides the Application and Expansion connectors found on the original KIM-1, enabling the use of original KIM-1 expansion boards.

NOTE: To do anything worthwhile with the Application connector you will need the PAL-1 2nd RIOT Expansion Kit.

Not all signals are routed to the Application and Expansion connectors because the PAL-1 doesn’t provide them, so there is no guarantee every expansion board will work.  However, Corsham Technologies’ and RetroSpy Technologies KIM-1 I/O and KIM-1 RAM/ROM boards have been tested and are compatible.

Available signals on the Application connector:

  • +5V
  • GND
  • PA0-7 (with installed PAL-1 2nd RIOT Expansion Kit)
  • PB0-7 (with installed PAL-1 2nd RIOT Expansion Kit)
  • DECODE ENAB
