Notes

A board that fits the ADAM with the General Instrument AY-3-8912 sound chip, the part that separates the machine from a ColecoVision carrying Opcode's Super Game Module.

Why it works

  • The Super Game Module adds two things to a ColecoVision: 32K of RAM and an AY-3-8910 series sound chip.
  • An ADAM already has the RAM. Adding the sound chip is therefore all that stands between it and the SGM software library.
  • The AY-3-8912 is the same sound generator as the AY-3-8910 in a smaller package with fewer I/O pins, which is why either part turns up in these projects.

Charles Lane - charlesmouse on AtariAge - discussed this board in the forum's ColecoVision and ADAM section; a comparable board was designed independently by chart45.
