The C version came later with the introduction of ASCII ( 5 to 8 bits ) and 110 baud. So it does not go back to the 50's.

The ASCII Teletype Model 35 was introduced in 1961. -pete On Tue, May 9, 2017 at 6:47 AM, Paul Koning <[email protected]> wrote: > > > On May 8, 2017, at 10:27 PM, Pete Lancashire via cctalk < > [email protected]> wrote: > > > > Bell 101C > > > > https://goo.gl/photos/hrhAwvzMBLWWteXu6 > > > > https://en.wikipedia.org/wiki/Bell_101 > > Interesting.
