Do any of you know a good place to find info on the VME bus on sun3 and
sun4 machines? Specifically, I would like to use one backplane for more
than one CPU. I have heard that this is possible to do with a few jumper
changes (for 2 CPU boards) but I'm not sure about the specifics.

Also, I have heard that it is possible to use a backplane for more than
2 CPUs with some hardware modification. Any details would be greatly
appreciated.
