[GreenKeys] Ebay Item - Teletype

[jhhaynes at earthlink.net]

I have the parts manual scanned.  If the other manuals are in the box I
haven't got to them yet in the scanning process.  As Jack says, it's an
oddity, not a useful machine.  It was supposedly intended for in-plant
communication where transmitter and receiver are on the same power system.
The principle of operation is to send a single pulse where the pulse
length determines the character.  The start of a pulse starts a shaft
turning in the receiver, and the end of the pulse causes it to print
whatever character on the printwheel is over the tape at that time.
