In the mid-late 1990s IBM used this card in most of their Aptiva systems. Basically it did the work of a sound card and modem, but very differently than most cards of its day. It was similar to a WinModem in that the host computer had to load software onto the card for it to operate, but the MWave used a DSP instead of offloading the work to the host.

This seemed like a good idea at the time, but the DSP was no quicker than a CPU would have been when it came to doing things like playing music and using the Internet at once. The OEM version would support a 28.8 modem and cd quality sound, while the Aptiva version would do 33.6 with a software upgrade. The drivers for these cards were quite flakey and the cards themselves often failed due to their complexity.
