I used 3/60 with 50MHz oscillator few years ago.
It almost worked fine, but sometimes dumped cores
with signal 4 and 11 in summer. ;-)
I think faster SIMMs(~80ns), faster CPU/FPUs (25MHz?)
and cooling chassis fans are recommended.

BTW, if you use NetBSD/sun3 on the overclocked machines,
you'd better modify delay_divisor value.
(now it seems in sun3/locore2.c)
