[GreenKeys] WU 22-A tape transmitter

[Chris Elmquist]

Hi Guys,

Found one of these in someone's basement.  I think they were discussed on
this list a while ago but I don't recall seeing any hookup or connection
info,

Do any documents exist for this unit?  Can it be used stand-alone or
does it need the rest of the TTY to make it go?

The earlier discussion suggested these were 1920-1930 vintage so what
model Teletype would it have been used with?

I can't do much with a 5-level reader here since I don't have a 5-level
punch but it's still interesting to me to know how these were used
(electrically).

73, Chris NØJCF
