OK, I think my web-based NABU Network emulator is in good enough shape to share!https://www.information-superhighway.net/nabu/The NABU was a Z80-based PC, released in 1983, that had all of its software delivered over a cable TV signal - like Sega Channel, but a decade earlier. It was only ever available in a handful of cities, including Ottawa, Canada, where it was developed.Leo Binkowski, who worked at NABU creating arcade game ports, kept virtually everything, so you can experience it just like it was 1983.
