Does the Original Series ever give any clues about how long transporters have been around? Not other series, not novels, not tech manuals (but the docu-book 'Making of Star Trek' would count), not Memory Beta, but the actual series.
I know in 'A Piece of the Action', Kirk doesn't try to explain beaming down to the Iotians, and they seem surprised by it. This would imply that the USS Horizon did not have that technology 100 years prior. 'Balance of Terror' seems to imply this (with the Romulan war being 100 years prior also). Both 'The Menagerie' and 'The Cage' show that the Enterprise had transporters 13 years before the series starts. Doctor McCoy never seems thrilled with the prospect of beaming anywhere, implying either he has a general phobia, or they are not THAT new.
Are there any other episodes or dialogue that would help nail down a time frame for transporters?
