Anyway, good memories, even in the tragedy. I can relate to people who resurrect GUS.
Since others mention similar failings of their card, I remember I too had it installed horisontally in a (Chinese/Taiwanese) mini-tower, it definitely wasn't a desktop chassis, much less an IBM PC. I guess gravity strained it to a breaking point.
P.S. When we invent the time machine, we should go back to load up on actual GUS _and_ spread the word for people to never install it horisontally :-)
Originally I was just using it as a Soundblaster, but in the last few weeks added Waveblaster, Adlib, and Gravis Ultrasound support. It's been a lot of fun learning how the GUS works and hearing how distinctively different it is from other sound hardware of that era.
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.
GUS selling point was offloading sound engine to hardware mixer, but by the time UltraSound PnP released CPUs were fast enough for fully software GM.
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.
The GUS soundcard just filled a niche perfectly at point in time with a reasonable pricepoint.
It came out at the same time as the Sound Blaster 16, but while the SB16 required "expensive" software mixing for anything but prerecorded audio the GUS handled that in hardware meaning that users either traded for CPU performance or audio quality in games.
In the 486 era it was really a differentiator and also caught on in the demoscene, by the time Pentium processors rolled in the software mixing cost became far less pronounced.
Finally when Windows became the go-to for games (and CPU's got even faster, esp when MMX processors came into play) the API's made cheap hardware equally good since most developers just targetted the plain streaming API's (with software mixing) for broader compatibility.
The final holdout for GUS cards afaik was the demoscene, since the card had a built in mixer with frequency control it could play modules (.MOD, .XM,etc) with simple players that just uploaded the samples to ram and then just changed registers realtime (kinda like an Amiga but more powerful) instead of including a mixer, in the end however it was more about code-size than cpu performance, doing a 64kb intro you could shave off something like 3-10kb's compared to supporting a SoundBlaster card (depending on other tools) and those extra KB's was well suited for effects/art.
In the end though, people realized that the dosextender+GUS combo was as heavy in terms of code as just a mixer on Windows (since you didn't need a dosextender) and when better compressors arrived for Windows even the demoscene moved on.
It was fun but I think my curiosity with assembling replicas of ancient tech is satisfied. This one looks more approachable.

...it's a breakout board for an OOP chip that's impossible to find?
You mean: ”I just asked Fable to one shot this and have no idea if it actually works”?
His "secret" is basically sanding. Lots and lots of sanding.

Still doesn't change the fact that this is an untested board design that relies on a difficult-to-source obsolete chip.
If some pins are swapped by mistake e.g. power and ground you are screwed.
Caveat emptor — unfortunately this was buried in the description.
Even if we assume this _could_ be one-shotted, projects like this from respected members of the retro hardware community would be what made that one-shot even possible.
At this stage in a project like this, I’d expect the people who were getting boards fabbed to also have the skills to sanity check the schematics and layout before they sent the gerbers off to China.
