Right.  "OLD" here means SunOS 4.

If you replace the SM100's with something a bit more modern (like SM41's)
then you will notice a large performance gain and be able to run more
modern versions of Solaris with a few caveats.  Even Solaris 8 will run on
a 4/600 with a minor kernel tweak if you don't care about the VME bus.
