there is an interesting project referring to retro-computing and arcade-recreation with the Vidor 4000 at this location:
a good guide to install the software on the Vidor is here:

i got it working nearly "out of the box"...
this project is pretty active (not in the forum but more and more Cores were released in the last weeks)

greetings and stay healthy...
