The 2060 was probably around 5 VUPS if I can trust my memory. Not until the 8350
(or was it the 8530) appeared did it match the 36 bit line in performance. I
believe some of the cancelled Jupiter work went into these machines. The 2080 would
have been about 20 VUPS minimum had it appeared but I'm less sure of that figure.
