EXT80A - External Expansion Card Adapter for the MZ-80A

This project outlines the design of an adapter which allows the Sharp MZ-80A to be used with a single expansion card.

Normally an MZ-80A would require the MZ-80AEU expansion unit to add expansion cards but these units are not freely available.

Either submit the latest release zip package in releases/ directory to a PCB fabrication plant or contact me as I may have spare.
