I think the 20 can actually do quad-CPU; while it has only two Mbus
slots, I seem to recall that someone made Mbus modules with two CPUs in
a single Mbus form factor.
It can do quad... Sun had the SM52X (2 SM51s on a almost
double wide cpu card... you could the put two of them in.
Downside was you lost 2 sbus slots. The Sun sold Hypersparc
module HS12 was a dual 100mhz cpu (I believe it was normal
width... so you didn't lose sbus slots to go quad).
If you went with Ross Hypersparc modules there were various
dual cpu on one module configurations.... I know there was
2 variants of dual 125mhz modules (256K, 512K, or 1M of cache).
I know there was a dual 142mhz 1M cache module (which I
believe was extra wide). Those are ones I have or have had.
There are many more.

Sounds like a sweet 20, alright. Whoever ends up with
it take good
care of it, 'k?
