Here is a set of photos from my NC (forgive any errors in my descriptions)

Here is a set of photos from my S model

I did not know originally that there were differences NC vs. S, until I
learned otherwise.  I had a bunch of boxes of NC and S parts, and it took
me a while to sort them all out into two separate and correctly-configured
machines.  So again I was learning as I went and some of the descriptions I
used to describe things in the posts above are sometimes sloppy.  Fun
project, learned a lot.

The more useful box is the S model because the more standard enclosure can
be used for testing other UNIBUS cards more easily or than parity RAM.

The thin 11/05 chassis I only worked on for a weekend.  MARCH (now
VCFed.org) had a pair and I went through them to set up for a demo.  No
longer in my hands.  I think these were used for small mini stuff and to
control larger minis.
