IBM?
I've acquired an Air Force manual describing Army, Navy, and Commercial Communications Systems. In the Army history it talks about an initial WW2 network using Morse via the Boehme system (Wheatstone tape keyers and inked tape reception) - and then 100wpm IBM radioteletype.....Whazzat??
------------
The Boehme System of transmission and reception was
inaugurated. This system had already been in use
in corps area nets and overseas stations as early
as 1937. This allowed the use of perforated tapes
for transmission of messages at rates from 75 to
150 words per minute.However, a radio operator
was needed to transcribe the inked dots and dashes
at the receiving end. Such circuits were operational
from Washington to domestic and overseas headquarters
stations during 1941.
b. Radio Printer Circuits. - Since transcription
was necessary at the receiving end, the
system was still operating too slowly. The next step
was the establishment of International Business
Machine (IBM) radio printer circuits. These circuits,
operating at 100 words a minute, offered
printed-page reception from special typewriters,
and eliminated manual transcription. Circuits were
established from Washington to Algiers, Casablanca,
Asmara, Hawaii, and Puerto Rico. This
system had many speed-reducing characteristics resulting
from the difference in tape width between
the ordinary teletype and the IBM machines. Therefore,
time was consumed in relaying from landline
to radio network, and vice versa.
