If you have an Major Havoc, Return of the Jedi, I Robot, or Firefox, your lovely four-channel sound is generated either by one very special chip, which Atari called the Quad POKEY, or by four individual POKEY chips mounted in a Quad POKEY Eliminator board.
Original Quad POKEY chips were always rare and those still in circulation suffer from the same reliability problems that plague the single-core POKEY. Any example of either chip is now over 40 years old and likely nearing the end of its lifespan.
Just as the PokeyONE solved this issue for the POKEY, the QPokey provides a modern, reliable replacement for the Quad POKEY. No bigger than a single 40-pin DIP IC, the QPokey plugs directly into the Quad POKEY socket on your Atari motherboard and SIMPLY WORKS, period. Don't get caught without a spare!
If you're currently running four POKEYs in a Quad POKEY Eliminator board, buy a QPokey and free up those four valuable POKEYs for use in your other Atari games! No more headaches from a cumbersome and heavy QPE board that tries like heck to pull itself out of its socket.
Just for fun, the QPokey is equipped with four blue LEDs, one for each of the four audio channels. When sound is played on a channel, the LED for that channel flashes in sync with the audio. Fire up Major Havoc or ROTJ and watch the light show.
