Reviving Retro Sound: New Open-Source Gravis Ultrasound Clone Emerges

Recreating a Classic

A new open-source remake of the legendary Gravis Ultrasound ISA soundcard has been released, bringing back a piece of gaming history. The Beavis Ultrasound remake was made available on July 15, 2026.

The original Gravis Ultrasound was a staple of PC gaming in the 1990s, renowned for its high-quality sound. The new clone is a testament to the enduring legacy of this iconic hardware. Enthusiasts can now build their own version using the provided KiCad schematics and PCB layout.

The Beavis Ultrasound project includes not only the KiCad files but also a sample ROM and reverse-engineered GAL logic. This comprehensive package allows hobbyists to recreate the sound card with relative ease. However, sourcing the necessary components remains a challenge for those without established supplier connections.

Can You Hear the Difference?

The level of detail in the remake is impressive, with the project's creators going to great lengths to ensure accuracy. By providing the KiCad schematics and PCB layout, they enable others to inspect and modify the design as needed.

One of the key questions surrounding the Beavis Ultrasound is how it will sound compared to the original Gravis Ultrasound. While the clone aims to faithfully recreate the original's audio output, subtle differences may arise due to variations in component quality and manufacturing processes.

The release of the Beavis Ultrasound is likely to generate interest among retro gaming enthusiasts and sound card collectors. As a result, we can expect to see a community forming around this project, with individuals sharing their experiences and modifications.
