OPL3LPT on Atari music replay sample
Channel: nokturnal
Date: 2022-04-26

Proof of concept of an adapter, which allows to use OPL2LPT / OPL3LPT devices with nearly any Atari 16/32 bit computer (Atari Mega/ST/e/TT/Falcon 030). Due to lack of proper signals and differences between PCs and Atari's some signals had to be rewired and repurposed. 
OPL2LPT / OPL3LPT is parallel port FM synthesizer soundcard with stereo amplifier manufactured by Serdashop. There are two versions with OPL2 (YM3812) and with OPL3 (YMF262) chip. OPL3 version can work in OPL2 mode.
