  - A Tektronix 4132 Unix workstation  using a
National 32016 CPU and a
 4.2bsd port called UTek 
 Gee, how does it perform?  I built a clone of a
Logical
Microcomputer Co. 32016 Multibus system and got it working.
But, it was glacially slow!  I did have some memory that was
likely a little slower than the stock memory, but it wasn't
insanely slow.  But, firing up certain things like editors
was just maddening.  And, I'm not talking about Emacs, just
vi.  I eventually got a MicroVAX-II to replace it, and, yes,
that DID have a cache to speed up the memory, but it was
quite a difference.
