I was hoping that the 601 Power Macintosh card in my Quadra 800 would go from 66 to 80MHz when I clockchipped the Q800 from 33 to 40 (since it will run at 80 in the 840AV). Alas, after a startup sound and a pause, it then goes into the chimes of death.
(Incidentally, since I don't see this documented anywhere: for the 4-DIP Mac Clip Jr, the 4 switches correspond to the leftmost 4 in the clock speed chart in the manual, starting with 38MHz { all down }, so 40MHz is dn up dn up.)
However, 8.1, 7.6 and A/UX are all very happy with the 40MHz upgrade -- even though Clockometer crashes in A/UX, Speedometer indicates an appropriate boost. So rather than having a crummy PPC running 8.6 occasionally, I'll just stick with a kick-ass 68040 running A/UX and 8.1 most of the time (and maybe 7.6 now and then).
