Do you have a 41C*? If it's a CV, you're in luck. There's an article in a
recent issue of Circuit Cellar that describes the resurrection of one via programmable
logic. That's the second article they've run (to my knowledge) that delves into
saving old h/w from the scrap heap. The earlier one uses GALs to replace the video chip in
an ELF. The latter uses FPGAs I think.
I'm not saying the author can or will supply the necessary code. But it's been
done at least we know.
