Made clean install of 8.6 to the 7100, but after that, i don't get *any* signal out of the Radius. I played around with the DIP-switches (i have two different, one with 8 DIP's and another with 10) but that did not help. Even basic VGA did not output. Gosh, need to get the Apple CRT from the basement, this isn't over yet! }

Radius webpage mentions compability for Macintosh II, Quadra and Powermacintoshes. So it should work out of the box.
