   I have to take a very slight exception to this.  From running
most of these machines side-by-side, I can say that a 4000/60 is
*quite a bit* faster than an SS1.  In fact, to me, it feels
noticeably faster than an SS1+.
I didn't say the opposite: I said that you will need at least a VS4k60
to outperform a SS1 as a VS3k1m76 can't. You confirmed my assumtion. :-)

A 4000/60 is about 1.5 times the speed of the 3100/76. How can you get the idea that 4000/60 will outperform the SS1, while the SS1 will run in circles around the 3100/76?

(The 3100/76 is rated at 7.6 VUPS, while the 4000/60 is rated at 12 VUPS)

Your numbes just don't seem to add up.

(Oh, and there are much faster 3100 systems than the 3100/76 around as well, but I'm not sure exactly when they were intruduced.)
