This and the MIA Pokey replacements for 7800 games. Convenient that 2600/7800 PCBs can use the same shells.
I would totally fund a Kickstarter to get shells made, and take Kickstarter exclusive color homebrews as backer rewards!
I have less control over the POKEY replacement, but I am trying to push it along.
Shells I have more control over, and that sure as hell is going to happen.
