Really?  Where?  The only docs I know about is the one I wrote!  I'm sure
DeQ has internal or maintainance info, supposedly CPU upgrades come with the
switch settings you need to run it.

I've never gotten my 500 clocked to 600 past the boot phase, 566 was doable
but the system seemed a very little bit unstable as a result.  I'm back down
to 500 as I want to keep this thing or long term.  That information was
mostly from an exercise to show it's possible so I can upgrade if I ever
find a favorable price on a 600+ chip.
