John and Park:

I think that your guess of "Tape Recorder Television" is correct.  What I am 
certain of, is that the machines had rather large, script-sytle lettering on 
the overhead doors above the transport which read "Television Tape".  That 
term continued to be used by RCA for years.  The use of the term Videotape 
was restricted for a while because Ampex claimed it as a Trademark. 
However, it was not legally registered by them, and they lost the claim to 
the term.  I have documentation on the full story of that somewhere, but 
can't locate it at the moment.

The TRT model prefix was never carried beyond the TRT-1 machines.  The next 
model introduced was the TR-11, the first of a series of non-sequential TR 
model numbers.  The third model was the TR-2!  Not to be outdone, many years 
later, Ampex gave us the VPR-6 after we had the VPR-80.
