The Opcode Super Game Module upgrades our current ColecoVision video game console from its standard 1 K RAM, with up to extra 32K (24) RAM. Both SGM1 versions of the Super Game Module has also a more avanced sound chip inside than the one in our ColecoVision. This avanced 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 an simple expander with more RAM and better sound, there is no graphic chip inside.
