The MicroVAX II was clocked at 40MHz (IIRC) and had a cycle time
of 200ns (no cache needed since main memory was able
to meet this).
The VAXstation 3100 had a 90ns cycle time. I don't know
at what speed it was clocked but the KA655 (also based
on a CVAX chip) achieved a cycle time of 60ns from
a 33MHz clock

The DEC Technical Journals are online, although the
first two volumes are *not* online. The rest you'll have
to get from old manuals and Sales Updates (the
Sales Updates back to 1994 were also online at one
point but I cannot find them right now).

All mine were free (except for one). It's just the luck of
the draw I guess.
