I have a used Saturn 3 from Varian which I believe to be in healthy condition since I'm able to successfully complete a full diagnosis cycle. However, I can't do a RESET (Ctrl + R). I'll get this error:

"Invallid PROMs installed"

This seems to be rather severe. Not sure what to do... I'm quite stuck. (The device is from 1994.) Thanks for any ideas/help you can provide!

Best regards, Stephan
