It would be nice to get more technical information on the 3B2s.  As late 
as 2016, I had reached out to Ed Eckart the archivist at Alcatel-Lucent 
and Seth had contacted William Caughlin at AT&T archives for more 
information.  Both seemed to indicate the systems were still in use at 
some customer sites and thus detailed technical info (eg. schematics, 
theory of operation docs, etc) could not be shared with the public.  But 
that sort of information was preserved and safe.

If anyone has contacts into either organization, a gentile nudge would 
be appreciated! :)
