Anyone able to capture Falcon 3.0 gameplay with an FPU on a 386? That would be pretty neat.

Good idea! Hope to see it.

It's not compatible with x87, so it's difficult to make comparisons.
They were supposed to be considerably faster, but you can't run the same code on both. You need specific applications for Weitek, and they're even more rare than x87 code in the 80s and early 90s 😀
They were heavily used in CAD applications and scientific computing.

Yup, the Abacus was a memory-mapped device. EMM386 even had a switch for it - EMM386 w=on .
The (dis-)advantage was, that this required the CPU to run in V86 mode.

Impressive! Did Quake support it?
