Fascinating thread! I wanted to implement 8-bit Atari in FPGA few years ago: http://repo.or.cz/w/AtosmChip.git Quite a lot of the logic seems implemented, but most of that is untested. I'm sure there is lots of small and bigger bugs. It's in Verilog and was mostly an exercise for me to implement something in this language. I simulated this code with Icarus Verilog, I've never tried to synthesize it for a real FPGA chip. The chips were not supposed to be replacements for the original ones. They are not compatible with the original bus, I used Wishbone instead: http://opencores.org/opencores,wishbone Maybe I'll continue this project some time this year, but I can't say anything for sure now.
