Zane, if you know, how can a single processor have a 4.5 to 1 ratio on
performance? The DEC document at
http://www.digital.com/timeline/1990-4.htm
says the 6500 was 13x a 780.
If so, then if people were thinking of a 58 MIPS 6500, this -certainly-
explains the performance difference. Heck, a 58 MIPS 6500 is even faster
than a 486DX4/100 !!!

You know, I'd love to experience something like a 6500 or some other fast
vax. It' be fun to "feel" it compared with modern junk.
Tnx again, nice pointer.
