PicoGUS is a project by Ian Scott based around the Raspberry Pi Pico, which originated as an ISA card to emulate the Gravis Ultrasound (GUS) for IBM compatible PCs. The GUS was one of the first wavetable sound cards, coming with 256kB (later up to 1024kB) onboard memory and hardware mixing of up to 32 sound channels, which made it extremely popular in the PC demoscene of the 90’s — and correspondingly expensive to acquire now due to their reputation.
Since initial release it has expanded to emulating SoundBlaster, Tandy 3-Voice, Creative Music System (CMS), Adlib/OPL2, MPU-401 intelligent mode (hello MT-32!), USB joystick support and most recently – acting as an ODE emulating CD-ROM drives on MS-DOS and Win 9x. For anybody who works with XT to 486 era PCs, the PicoGUS is nearly a must-have, combining so much (often expensive) functionality into a single card. In my own 486, I switch it between acting as a GUS for running vintage demos and being an MPU interface for my mt32pi.
Visit the project’s homepage for more information, and the the source code and hardware information is hosted on GitHub. Ian Scott also has a number of overview and demonstration videos of his own available on YouTube.
