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.

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