[RTTY] When did mechanical teleprinters become obsolete?

[ad0k@inbody.net]

We were using mechanical machines on Navy ships until the mid 1980s at least.

When I worked at DYE-5 in Iceland on the DEW line from 1977-1979 we still used a
TTY machine to send our daily reports.

Never saw another one in use since I left there that I can remember.

It was a lot of fun to compose the daily report and run the tape.  Luckily we
didn't have to service the machine!  We left that for the military techs.

I was just thinking (dangerous, I know) this morning about the history of RTTY,
and I wondered exactly when did the use of mechanical teleprinters become
obsolete? Now, back in 1975, there was a fellow who adapted a terminal unit to
an Altair 8080 and was participating in the BARTG contest while he was
exhibiting at an Altair competition. He won the price for the best application
of the Altair computer.

So, that's probably the earliest mechanical teleprinters were replaced -- but
when was the last year that they were used on the air?
