From reading the NAVSHIPS for the TT-47, it looks like one of the 28s
for which I have visiting privileges is in a CY-870/UG cabinet. I can
see that the 47 and 47A used the 870 cabinet. The 47C has the more
traditional cabinet. There is no NAVSHIPS for the 47B, so I don't know
about that version. Why do I care? I want to print the most
appropriate schematic/wiring diagrams in preparation for my next visit
to the "warehouse".
May I assume that the change from 3-10 point terminals strips to 2-20
point terminals strips took place with the change from the CY-870? Or
was there a mod-kit for the CY-870?
I know, I should be taking pictures of name plates etc. Turns out that
of the three machines. it appears to be one from WU, one from Navy and
the 3rd a Bell/AT&T version. I was spoiled with my source in the 60s
being all Bell System machines.
