Four of them??? Surely not!
You can plug in two 200 (225???) MHz cpus, but that would not
gain much compared to the four 95 MHz cpus. I'd even say the
four cpus are better cause it's harder for a single person to
occupy all cpu horsepower.

They never sold any machine with four SM-61 or faster. The
only four CPU configuration that sun supported ever was the
SS20-514, e.g. two 50 MHz dual cpu modules with 1MB supercache
each. The reason was simple: Four 60 MHZ (or faster) would
clog the M-Bus and run slower than four 50 MHz cpus.

Notice that the Hypersparc have only 256 kb cache...
