What is that used for?
it's the IBM Music Feature Card, the first PC sound card, that was competing alongside the AdLib and LAPC-1. the AdLib was a lot cheaper and simpler and ended up murdering it, and it was sold only as an IBM option, so sold poorly and is rather rare nowadays. a bunch of Sierra games support it.
