I had an idea... yank a video card out of IIsi and stick in a IIci. If
the major problem is the video allocation then if I stuck in an
alternative card, maybe that would help. I had one other thought, maybe
netbsd 1.0 will run great on my IIci. If that's the case then it's
definately worth going back to an older version. Let me know what you think.
