	Apollo dropped off a 3500 for us to play around with for a while.  I
had just been playing with a program called paranoia which is supposed to test
floating point thingies, and tell you how good your machine-compiler handles
floating point arithmetic.

	Only one machine passed the test, out of the 3 I tried it on, and
that was a mVAX II running Ultrix 2.3, both the Apollo and an HP9000/350 SRX
crapped out.

  Machine(config)	Time to compile		Bombed at what point.
-------------------------------------------------------------------------------
dali HP9000/350 SRX
25mhz 020, 881 fpu        40 seconds		Just after milestone 30 with	
running HP-UX 6.0				Div lacks Guard digit, IOT
						trap, (core dumped)

bridger Apollo 3500
25mhz 030, 882 fpu	127 seconds		pow:DOMAIN error, then goes
running SR10.0					into infinite loop, which
						even kill -KILL pid doesn't
						stop.

caesar mVAXII
whatmore to say??	101 seconds		Completes the test, says
Ultrix 2.3, with pcc.				it has one error.

	While I realize this is one very limited test, for the combination 
of what works, versus performance, the mVAXII isn't bad is it?  I'm suprised
by the pathetic compilation speed of the 3500, sounds like some serious
C compiler work is needed here.

I'd be happy to send the source to anybody who wants it.
