go-8080

an Intel 8080 emulator written in Go (Golang)

(also contains a minimal implementation of CP/M to run CPU tests)

• It passes (almost) all CPU tests that I could find. Run

go run . /path/to/cputest/file.COM

to see test output. (Warning: 8080EXM.COM takes quite long to finish and tells me I still have a bug somewhere.)

• It can be used to emulate the Space Invaders Arcade Cabinet, see my implementation
