The program will only run on a CoCo 3 tweaked with a Hitachi 6309 and 512K of RAM.
Very cool project though.
6502 and 6809 are the favourite CPUs of my youth (the Z80 and 8080, not so much).
I had a Coco and a Coco 3 in the 1980s and was always a little resentful that other computers like the Apple ][ had more software. This emulator would have delighted me back in the day.
Same here. Also wonder how much of impact it would have had on the CoCo3's sales had John Kowalski's Donkey Kong transliteration been written back then. Even if he couldn't get a license from Nintendo to sell and distribute it, think it would have knocked everyone's socks off at the time.
It would have had little to no impact. To run it, you need the 512KB upgrade and a disk drive. To get decent looking graphics you'd also need to shell out money for an RGB monitor. It would have been substantially cheaper to get an NES and the DK cartridge for it.
It was insane how many peripherals Radio Shack sold for the Coco, I'm certain I spent more on Coco stuff from 1980 to 1987 or so than I did on the 286-based computer that I replaced it with. The 286 started out with a monochrome display and was crazy powerful (could emulate a Z80 running CP/M at more than 3 times original speed) but didn't have an operating system as good as OS/9 which, for the Coco3, had a windowing system a bit like Plan 9.
