Manila Gear released the new 0soniq, which gives you zero channels of sound for your Apple IIgs, instead of the usual one.
Each of the 32 oscillators available in the Apple IIgs’ Ensoniq Digital Oscillator Chip (DOC) can be assigned to play on any one of 8 output channels. The 0soniq blocks all 8 of those channels. If you would like to hear those channels, check out our 2soniq stereo or 4soniq quadraphonic sound cards.
To enjoy no sound with the 0soniq, simply plug the device into the 3.5mm female audio jack at the back of the IIGS. * Almost all software written for the Apple IIGS supports at least 2 channel sound.
