Chris - This project is moving along nicely, it's exciting to watch it evolve. One suggestion to consider - perhaps there is a way (socket?) to accommodate some sort of chip from Diego, to allow "insertion/upgrade/whatever" enabling use of ROMs (RAM, etc.) using his NoV-64d design. This single socket would basically open up the design to allow use of ALL the 41 ROMs, including esoteric stuff like CCD, HEPAX, Zenrom, etc.

I've no idea if Eric's code even accommodates expansion ROMs, etc. so this may not even be feasible, but it would dramatically expand what one could do with this DIY 41C, allowing folks to buy an upgrade chip from Diego if they desire to expand their system.

Just an idea...
