Yes I've opened it further but I didn't have tools with me yesterday so
I didn't open it further then and take more pictures. Behind the panel is a
bunch of core memory boards and some other cards. I don't remember much
about the other cards but I have some of the core boards here at the house.
I'll photograph them and post the pictures later today.
This is an interesting find....
Yes, they are. I found several of these and some UYK-44s about a year
and half ago and never got around to doing anything with them. One was
baddly damaged and partially stripped so I took it apart for the cards. The
others appear to be intact.

You have the manual for these? Any chance of borrowing it? Or at leasst
getting a copy or PDF of the descriptions?
They use a crap load of these things onboard ship. If you search the net
you'll find dozens of references to them being used for fire control
systems, navigation, communication systems, cryptography etc etc.
Somewhere on the net is a photo of the radio room of one of the big
battleships (USS Missouri?) and you can see one in the photo.
BTW IIRC I found a date of 1968 somewhere on one of these.
