There are many types of ring oscillators with quite different characteristics, such as temperature stability and resistance to interference.

I was hoping this would be a development board with multiple types of oscillators but this doesn't seem to be the case?

Pretty cool, but tbh per the author/equipment list this paper is basically an advertisement.

Not so sure. I did not find the eurorack module they reference there, even on the analogue computer's manufacturer website.

The modules they use seem to be fairly standard stuff, like the digital potentiometers, analog summing circuits and such.

If they already got the modules then no need to invent new PCBs just for some early-stage research.

It's kinda the other way around. They're using oscillators as a means to an end, ie solving physics and math problems based on the Ising model[1].

While the Ising model was created as a model of ferromagnetism, and is deceptively simple at first glance, it's turned out to be quite versatile[2] and can be used to tackle many different problems[3]. However computing solutions can take quite a lot of computing power, and this analog solution supposedly can potentially do it faster.
