Zane,

ITYM "MIPS".  It's not a plural, it's an abbreviation of "second".

Anyway, although Digital's marketeers tried to claim that the 780 ran at
1MIPS, it was clearly doing about half that in any decent benchmark.  That's
the reason they came up with the VUP, very quickly.  AFAIK, no one else ever
bothered to use the VUP as a measure, even if they were into MIPS.

                                                                Rich
