What does it take to be a VHDL programmer?
I don't know much about it, but I used to do some 6502/6510 programming in assembly and machine language in the 1980s when I was a teenager.
I'm from the USA and I'd like to help but I don't know how.
I know the Commodore 128 used an 8510 CPU and simulated the Commodore 64 mode sprites using software instead of a VIC chip. I think they did that to save money.
I think the goal should be to get a Mega65 with C64 and C65 mode working and earn money to pay more VHDL programmers to emulate the other 8-bit systems or even a Z80 CP/M-80 mode.
