I got the card working much better now.

Using the win3.1 setup disk acquired from archive.org's time machine I was able to install the necessary drivers to get win3.1 up and running in much better shape than win95.

Programs run, things work. But its clear I will need a co-processor to do anything really exciting with it. Still, I press on!

Questions for the informed:

-I have seen discussion online of the PowerMac 7100 being overclocked. Does anyone have any links where I could find more information? Everything I find discusses the why and what, but not the how.

-Does anyone have any advice what kind of coprocessor I should be looking for? More details and photos could be provided.
