Fantastic addition to the PAL-1 system

This addon was straightforward to put together and worked perfectly once assembled. The pre-programmed ROM comes loaded with useful monitors and languages:

eWoz, PBug, MS BASIC, Apple I Integer BASIC, VTL-02c, and a Memory Test Utility.

Kinda requires the RAM expansion, so go grab that too!

Response from KJXZZ | July 18, 2022

Thank you for the review!

The ROM expansion brings PAL-1 a good usability.
