The Sanyo Y4AA is a lightpen that was provided with the MPC-11 computer.

Differences with the MLP-10 lightpen provided with the MPC-10 and probably the MPC-10mkII are unknown. It's maybe the same lightpen!

The Y4AA lightpen was also available separately - Official price: ¥14,000


  • This lightpen requires a computer with lightpen connector and built-in MSX1 lightpen interface, so the choice is limited to the three mentioned computers and the MPC-X Graphic Expander Unit.
  • A lightpen requires a CRT display. It cannot be used with modern LCD displays.
