John, I tried this today on a IIx MacIvory running 8.0.1 with the Symbolics Keyboard and Mouse. So far, no problems as long as Mac virtual memory is turned off. With virtual memory on, it crashes my IIx shortly after trying to start Genera (blank gray screen, no menubar, can't even get to MacsBug) requiring a restart via the hardware reset key on the side of the Mac.
