Well, my first posting may have given a too rosy picture about the 2 CPU
500 vs. the 1 CPU version we started with.  But, there was a tremendous
improvement with 10-15 people logged in.  With our new 3CPU configuration
we hope we have a machine that we can use until HP comes out with something
very powerful that we can use as an instititue central computer.

Until then we invest in 350s (/370s?), Woolongong TCP/IP (!) and, maybe a 835
for dedicated purposes.  My "own" 350 with HPs FPA plus the Ariel FFT-card
is also VERY fast and I use it both in my office and in field experiments.
I hope the announced new 68030 upgrade card will not be too expensive since
I need all the power I can get in time-critical applications.

Unfortunately, I don't get all the money I want and HP only gives away
computers for free to Computer Science Depts ...
