Soldering the Tandy Retro Soundcard TI SN76489
In this video I am assembling the Tandy soundcard by matze79. This piece of hardware was triggered in this discussion on the Vogons forum:

The Tandy PC series was a PC compatible range of machines by Radioshack which incorporated their own graphics and sound standards. The centerpiece of the card is the Texas Instruments SN76489 chip, which generates three channels of monaural, squarewave voices. A great range of MS-DOS games supported this sound standard. The Tandy sound and graphics standards were more or less a ripoff of IBM's PC Junior standard, which in contrast to Tandy, failed to gain any significant market share.
