Beavis Ultrasound PnP ISA Sound Card Replica

Man, throwing away a GUS Classic 20 years ago alongside a bunch of other obsolete PC hardware was something I still regret to this day.

The GUS was such a fantastic card. I didn't have much money as a kid, but found a very heavily discounted GUS Classic around 94 (probably because a newer model was out). I harvested RAM from an old videocard and bumped the RAM up to 1MB that way. Being able to load up your own samples and using them in your games, etc. was a lot of fun.

The card fried at some point because it was so heavy that it bent and hit the bottom of the PC's chassis.

Later I got a GUS Extreme, which had 1MB of RAM on the board already and an ESS AudioDrive chip. Though I experimented far less with this card.

We also had their gamepad at some point.

For what it's worth, if you don't have the chip that powers this card, there's also the PicoGUS which is a multi-function, software-defined ISA card that includes the ability to emulate the Gravis Ultrasound among other sound cards: https://picogus.com/

The Gravis Ultrasound had an incredible price to performance ratio back in the day and made high quality wavetable synthesis at "CD quality" available to the masses.

Edit: The fact that quite a few games supported the GUS out of the box or received patches to do so was also a well received boon on my side.

Cool, I saw this one pop up on tindie a few months ago, sold out instantly... https://www.tindie.com/products/kdehl/gravis-ultrasound-gus-...

Oh wow thanks, I had completely forgotten about the Ultrasound even though I loved mine back in the days.

I think the main problem will be sourcing one of the AMD InterWave chips. Those are (to my knowledge) not produced anymore and the only source would be another GUS card

> If you want to build this board, first make sure you have an AMD InterWave chip, the AM78C201. The design of the card is quite simple since essentially all sound card functionality is built into the AMD chip.

...it's a breakout board for an OOP chip that's impossible to find?

” Note: I have not generated the fab package since I have not actually fabricated the board and tested it for functionality. Build this board at your own risk.”

You mean: ”I just asked Fable to one shot this and have no idea if it actually works”?
