That's great! The radio station I worked in in 2970 had a Lenkurt
demodulator driving a model 15 for the news wire. Anyone notice that the
punched tape on the cover was 6 level Teletypesetter code?

This was all leased line voice grade communications where a circuit might
be idle much of the time. Packet communications sure improved circuit
utilization!
