Thank you.

Yours uses high end i860 chip.  Man!  My face is green with envy now :-(
I certainly know how to put 80 MFLOPS into good use :-)

[some stuff deleted] 

 Our EECF (electrical engineering computing facility) here has a multi-i860  
machine made by FPX (I think) running multiprocessor SYSV UNIX.  If you need
more info, please email me and I will give you a name for more.

I like to hear some insight info about this too.  I also have been curious for
quite a while already.

Hmmm.... really enticing.  A beauty indeed :-)
