That PCB looks very much like ones I bought many moons ago that had come
from original IBM mainframes. I suspect the logo is the PCB
manufacturer.

Oh, my goodness. Where did you get that ...

The company I worked for in NZ handled Inforex key to disk/tape
machines, that is the program memory PCB from one. The piggyback PCB in
that photo covers the actual core memory area - yes real magnetic core.
The disk drive had mechanical detents to keep the heads still once at
the track position. They were used by Databank, who had a number of data
entry branches around the country. I worked in the room next door to the
guy who did the PCB repair. 

The PCB in the first photo is definitely not an Inforex one, all the
Inforex ones were of the same size and finish as the second photo. Any
smaller ones spread around the machine were not in card cages, but had
the tin finish, not gold.

Boy, memories of the Inforex machines bring back recollections of
stories from the guys that did the callouts of rooms full of rabid
keystation girls. They reckoned you were lucky to get out with your
clothes intact at times.
