When the gentleman who did them gets back from his honeymoon I'll
ask him for more details.  (assuming that the results are considered
public domain, which they may not be)

I don't know about the symmetrics box, but I've heard that our customers
have found the Tek 6130 (32016 @ 10MHz) to be faster than the Sun-2.

I work for Tektronix, not NSC.  My current task is doing bugfixes and
enhancements on UTek (UNIX) utilities for the 6130.  I do as much
of my work as possible on doghouse (6130) because it's so much faster
than hammer (Vax780).  (Unless there are only 1-2 people on hammer,
which is pretty rare)

No, the 32016 is a 48 pin dip, the 32032 is a 68 pin leadless chip carrier.
The Tek 6200 series had sockets for both.  Conversion was simple,
just pull out the 32016 and put in a 32032, and *presto* it runs faster.
Unfortunately, the 6200 series was cancelled for political reasons.
