On Tedium, Ernie Smith writes a brief history about sound cards.

Nor was it the only major player in the market. Also in 1987, a Canadian company called AdLib was the first major player to the musical computing market, and its device proved an early success. These cards relied on the Industry Standard Architecture, or ISA, expansion slots that had been common on IBM PCs since their 1981 release.

Several takeaways from this.  I had forgotten about AdLib and how they were a major player in this space back then.  Also, the fact the so much time has passed that Ernie has to explain how in the pre USB days, computers had slots for expansion cards and drivers had to be written for every app.

Kids have it so easy these days. 🙂
