[SunRescue] Upgrading the CPU/FPU on a 3/60?

[Paul Khoury]

I was reading up on sun3arc.krupp.net about upgrading the CPU/FPU
from my 3/60.

It means I can get better FPU performance if I stick in a 68882 FPU replacing the 68881.
It also mentions it has to be pin and command compatible.  Would one from a Mac fit the bill?
I somewhat doubt it, but thought I'd ask - came out of a IIfx.

Also, has anyone had experiance with overclocking their sun3's?
