No answer, but a comment:

Beware of HP's claims.  Their machine is *hot*, but they tend
to be into hyperboil (?sp).  See Dvorak's column in PC Magazine,
where he reports HP's claims of a 720 vs a Cray, and interprets these
with a wise ton of salt.

The HP videotape I saw cited a SAS developer compairing SAS on the
HP versus SAS on a 3090-600E.  Only problem is,
SAS/C (in which SAS is now written) does not,
to the best of my knowledge, take advantage of the IBM vector facility,
multitasking, or QSAM chaining; the comparison was a little skewed.
I would also use the caveats suggested by Dvorak, in terms of
scalability of the comparisons.

Mind you, I repeat: the 720 is a *hot* machine!  And the PC simulator
beats pcsim by miles.
