SUPER GAME MODULE (SGM)

The Opcode Super Game Module upgrades our current ColecoVision video game console from its standard 1K RAM, with up to extra 32K (24) RAM. Both SGM1 versions of the Super Game Module has also a more advanced sound chip inside than the one in our ColecoVision. This advanced sound chip was one of the most known out there in the 80's, namely the AY-3-8910A. AY-3-8910A was already a known audio chip, for example in some MSX computers and earlier arcade machines. The Super Game Module 1 is just a simple expander with more RAM and better sound, there is no graphic chip inside.
