What is it?

The Brain Board ][ is a revision of Mike Willegal's Brain Board, done under GPL.

Why did you make it?

I made this revision to accommodate a larger ROM (Manual bank) and make use of the un-used dip switch in the original design.

What makes it special?

This board allows you to run Integer BASIC or Apple 1 emulation (Wozaniam pack), and can be configured to toggle between 2 on-board ROMs, or an on-board ROM and the system ROM.

See my recent blog about using this for both Apple-1 and Integer BASIC while retaining your system ROM access:

PCB's are ENIG, not HASL, and have a beveled edge connector. Kits come with a parts list, however, full documentation is on github, and this project assumes a base/moderate skill level with soldering thru-hole components.
