Yes, I've had a look through all them, thanks for saving them!
To say a bit more about what each one is (as best I can work out), let me
start with the one labelled "The whole group" (which will allow me to name
them all, for talking about the rest of the images).
That shows (from left to right) one of these non-Multics 6000 series CPU
panels, and then what seem to be 5 IOMs (Input/Output Multiplexors), of three
different types. The first, second, and fourth all match. The third is
identical to the one shown on the MIT Multics machine, here:

Alas, there don't seem to be any closeups of this panel, which is a real
pity! Oh well.
The fifth is similar to the set of three, except that it is missing the
'Configuration' sub-panel in the lower right corner. This is thought to be an
IOM since there some closeups of it, which allow the labels to be read, and
these seem to indicate that it's an IOM. As to the other three, although
there are no closeups, since they match this one, they are thought to be IOMs
also.
I wish I knew why there were two different kinds of IOM panel, but I'd
only be guessing - I haven't seen anything in the manuals so far.
For the discussion below, I'll call them IA (the set of three), IB (the short
one), and II (the one like the one on the MIT 6180).
OK, so here's the rundown on the rest:
- The first 6 show the 'short' IOM (type IB)
- The next three seem to be the back of a Multics CPU panel
- The next is the back of a type IA IOM
- A non-Multics 6000 series CPU
- The type II IOM
- The next two are type IA IOMs
- The type IB IOM
- The whole group
- A Multics CPU panel (this may be the one that went to the LCM?)
- Another image of the back of that
- The next four are details of the front of the Multics CPU
- Then two more images of the back of it
- The front of a non-Multics 6000 series CPU
- The back of it
- Finally, three detail images of the front
I _think_ I have them all right - if not, apologies!
