[GreenKeys] Modems and CCU's

[Jim Haynes]

OK, that CCU looks like one for Telex.  The one with two "Centronics"
connectors is for TWX and 99 of the 100 wires are used.  The real name
of the connectors is Amphenol Micro-ribbon, but they get called
Centronics because they are most familiar when used with that make of
printers for computers.

There is some information about the Telex equipment in Western Union
Technical Review.  In particular see the article in Vol. 17, No. 4,
starting on page 134.
