Does anyone here know when Moore Reed first marketed their extremely popular (in the UK!) acoustic couplers (telephone modems). Here's an example:
https://blogs.ethz.ch/its/2022/03/22/it-find-series-1-2022-what-do-you-think-it-could-be/
It's the _date_ I'm interested in. The few sources that I've found date it to 1980; but we have three, and two of them have been dated to the 70s (1970 and 1974). Those dates may well be erroneous, but '1974' was recorded by our founder (now passed on to the great collection in the sky), and he actually used one of these things.
Thanks for any informed speculations or even facts ;-) [1]
In the movie "War games" appeared an acoustic coupler. I have no idea
about the model. Movie is from 1983. I knew already about those devices
when I saw the movie.

The device on top of the screen and under the speaker being fondled by
Ally Sheedy here:
http://pc-museum.com/046-imsai8080/wargames-08.jpg
Is actually a direct connect modem, A Cermetek 212A. I have an
identical unit that hasn't been rebadged.
$deity knows why they had a direct connect modem there doing nothing
_and_ an acoustic coupler in use. I don't recognize the acoustic.

I was using acoustic couplers to dial up in 1978, maybe 1977.

The amusing thing about those scenes is that the data seems to
be flowing at about 9600 bps. A bit of artistic licence, there.

i'm sure they didn't want to spend half the movie waiting for
120cps (or whatever it was). i do recall that i could read the
teletype as fast as it could go without any problem (late 70s)
for the connection we had.

I seem to recall a max of 3 character times, depending on what position
the print head was in. In another life I wrote a TTY driver fir CICS.
My recall may be faulty.

i'm pretty sure it wasn't 300cps as i recall it being
pretty slow. of course we were playing space wars or star trek. :)
