The TI 99 4/A was released in 1981. The sound of this nice home computer was the Texas Instruments SN76489 the provides 3 audio channel for notes and 1 channel for noise.
It’s a little boring to program (the CALL SOUND subprogram) so I thinked to sample the TI99’s sounds and put in a floppy for the Roland S Samplers.
