@lupyuen I rocked a Voodoo 5 5500 for about 4 years back in the day. The Omega drivers extended its usefulness with Glide wrappers for OpenGL, and increased its lifespan dramatically. It was the first card I had that used an external power source, a MOLEX connection. Dual GPU on a single card. Those were the days, when technology was held together with duct tape and dreams. 😁

PINEBUDS UPDATE:
Pine64 has fixed the issue already by swapping the tape out for hot glue. While it isn't what I would have done to resolve the issue, the battery stays in place now so it's all good.
