A sound card before its time
 

A mysterious full-length sound card recently arrived at the OS/2 Museum. It was clearly manufactured by IBM in 1985, and sports a 20 MHz Texas Instrument TMS32010 DSP (the DSP is the large black DIP chip near the lower left corner, not the ceramic gold cap chip).

I love a good hardware mystery.
