Make Your Own ColecoVision at Home

I dunno if the SN76489AN is software compatible, but there's a few companies making modern AY-3-8910 (the sound chip in the Master System) equivalents. There's the JFC 95101, and I believe the Filfact KC89C72, though the origin of that one seems quite strange; zero information on the company that makes it or what else they make is out there.

We had Intellivision in the US. Growing up, I had a friend that had one. The Atari was more popular (and cheaper) as I recall, but Intellivision was definitely were a presence.

Intellivisions weren’t as common as Ataris in the US, but I knew a bunch of people who had one.

Colecovision technical specs are better than the Mattel Intellivision, which are better than the Atari VCS.

The Colecovision has the same video chip as the MSX 1 systems, TI-99/4A, Thomson MO5 & TO7, and Oric, and the same sound chip as the BBC Micro, IBM PCjr, Tandy 1000 and Sega game consoles.

The Mattel Intellivision video chip was not used in other systems. The sound chip was used in the Apple II Mockingboard, MSX 1, Oric, Vectrex, Amstrad CPC, and ZX Spectrum 128.
