Sound of the 90s: The Gravis Ultrasound Card Revival polymatt 2024-01-12 | "If it didn't play Doom, no one was gonna want to use it."You can visit patreon.com/polymatt to support my work and get early, ad-free access to my videos as well as other perks!The Gravis Ultrasound is a long sought after card from the early to mid 1990s for it's unmatched ability to generate realistic audio with it's wavetable synthesis. Not many were made, not many games were supported but it earned a cult following. Fast forward to 2023 and they're almost impossible to find at a reasonable price. Enter Ian Scott a.k.a polpo. He took his #raspberrypi project to the next level and built a faithful reproduction of the Gravis Ultrasound card... and more.Let's catch up with Ian and see what the genesis of the project is and what might be next on his radar.
