Build a 6502 Computer
David Murray (aka the 8-bit guy) has a plan to build the "Commander X16", a new 6502 based computer that is philosophically similar to a VIC-20 but has more RAM (2MB), a higher clock (probably 8 MHz) and an FPGA to do VGA video. It might not be on the radar of people here because of some odd choices, like using a Facebook group as the primary discussion forum.
