Can vouch for the sun-4 stuff.  The stuff I do was the original basis
of the claim.  I run a virtual drumset (polhemus, hidden line removal,
etc.) and still have enough time to run csound real time option for
the sound (on a SparcStation 1).  In general sun 4's can handle
csound real-time generation stuff easily (8k, mono).
