easy to become confused with teletypes ;-)
I have all of the documentation (I believe) is
available from PDP8.net.
A fine starting point.
I have carefully checked it out mechanically and
(non-powered) electrically
as best as I am able. The only question on this fromnt is one switch which
appears to be out of position, but I can

Yes it is out of position.
Compare with "Figure 5 - Typing Unit" on Page 8 SECTION 574-122-702TC.
You can see the correct position in the FORM-OUT MECHANISM area.
The contacts are the INTERLOCK CONTACTS used for stopping the papertape
reader while doing a formfeed. (Only used in sprocket feed assemblies).
What I can not seem to find the documentation for is
the interconnection of
the various Molex connectors:

You can get a pdf file from my
website showing the wiring diagram for an
ASR33. This IMHO gives the best overview about the Molex connectors.
It is located at

Hope this helps
