I have all sorts of numbers somewhere at home, mostly comparing CYBERs to VAXes. Plus I did a fairly comprehensive history of the CYBER models over time with their approximate speeds (again somewhere at home). About the only number I can remember off the top of my head is that a dual cpu CYBER 865 was good for about 26 mips. I think that is about right. We old CDC gurus are beginning to lose our memories.
