Yeah... I was mostly joking about that anyway, putting video chips into a
cart. It would have been a cool thing for a company to do back in the 80's,
but not something I'd seriously do as a hobbyist. Even if I got the thing
designed, it'd cost a fortune to make them, and the program for it would
be useless without it. Also, if I wanted to use a framebuffer, there's always
the Atari 1200XL up in the attic :)

qbasic?? *shudder*

I'd use perl if I were in a hurry, C if I were doing it for work :)
But then I'm doing everything in Linux, except running z26.
