Anyone got any memories or info on an early to mid 70s
ICL mainframe that
required a big keyboard known as the 7181/9? I've got one and I'm sure it
was used on the 2900 mainframes and maybe earlier - big desk console types
with built-in monitor but free standing keyboard......
We never used those particular devices at our installation, but I did see
some info on them (I think there was also a 7184 of similar nature).
These were synchronous, block transmission terminals - a screenful of
information was sent at a time (either system -> terminal or terminal ->
system). Used on the 1900 series and perhaps 2900s. Normally connected via a
7900 series communications processor (better known as a PF56), but some of
the last smaller 1900s (1901T & 1902T) had a built-in adaptor.
