Sound Devices Supported : Tandy / PCjr
One of the evolutionary steps IBM took was embedding sound capabilities into the PCjr. The PCjr contained the TI-SN76496 3-voice sound chip, which could also produce a fourth noise channel.
Most Tandy 1000 models have this chip as well, as they were clones of the PCjr.
You can hear examples of this chip at That Oldskool Beat, and can run programs that support it under Tand-Em, the Tandy 1000 emulator.
Tandy / PCjr is part of the Sound Devices Supported category.
