- CYBERs were 60 bit machines except the newer NOS/VE machines which were
- 64 bits.
-
- 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.
