Does anybody out there know of similar documentation for the 8*24 GC board?
I miss the extra pixels of the Toby frame buffer as much as I like 24-bit
color... 

Given the expandability of Video RAM on the GC board, I can believe that
pulling the same trick that MacAppleZoom does would probably be possible,
perhaps even easier than with the Toby/Mac II Hi-Res board.

Anyone know?
