Atari TT Fast Rom

Post by Icky »

Has anyone thought of or built an Atari TT Fast Rom board similar to how Exxos does the ST Fast Rom?

I did try on the MSTE once, but the GAL code floating around seemed buggy :( I thought of just running the CPU at full speed on ROM access, it would only need a small GAL change, but even getting the stock machine to work , well, didn't.
