[GreenKeys] Two Teletype model 20RO printers available

[Sheldon Daitch]

Just a bit of trivia, Randall.

The Associated Press in North Carolina still had Model 20 papeprinters and tape punchers at subscribers as late as early 1979.

The Durham Herald-Sun was still doing hot lead typesetting from the tapes in 1978, but as I understood it at the time, they werevery close to converting over to offset press operations and that would eliminate the tape and tape reading Linotype machines.

I received the below email from the Denver Telecom History Group. THG
currently has enough Teletypes (and I'm working on getting them running).
So, the below listed equipment is available as described below (trade for
model 15 or pay cost). Please contact Randall directly.
