[GreenKeys] Teletype Monopulse printer

[Duncan M. Brown]

I just came across a good description of the M36 in a Teletype Corp.
document.  (Note that TX & RX  do require the same 60 cycle power source
for synchronization.)

	TELETYPE MODEL 36 (MONOPULSE) TAPE PRINTER SET


		The Teletype Model 36 Monopulse printer is a simplified printing
telegraph device designed to supplement conventional Teletype apparatus in
local circuit applications where printed message service is desired but
where the traffic is not sufficient to justify the installation of standard
Teletype equipment.  With Monopulse equipment, letters, figures and the
dash symbol (-) may be transmitted at a maximum speed of approximately
twenty words per  minute from a compact circular keyboard which is
alphabetically arranged. Selection is obtained through variations in the
length of single pulse signals originating with the keyboard transmitting
station. The set is particularly adapted for economical printed
intercommunication services in offices, stores, banks, railway stations,
factories warehouses, yards, etc., where all stations will be located
within a limited radius and have access to the same 115 volt 60 cycle power
source.  Monopulse equipment is not adapted for operation with other
Teletype apparatus, and because of this and other limitations is
recommended for local message service only. For general communications
service over extended circuits see Teletype Model 14 and Model 15 printers.
