AY et YM (Edit)

The AY chip, also called SSG or PSG (Programmable sound generator), is a sound chip able to produce square waveforms and noise.

The Atari ST has the Yamaha YM2149F chip, like on MSX computers, almost the same used on the Sinclair spectrum ZX 128, the Squale (AY-3-8910) and Amstrad CPC (AY-3-8912).
