[GreenKeys] Re: Lorenz Model 15

I meant to comment on this earlier.  Lorenz in Germany produced the Model 
15 under license from Teletype beginning in the 1930s.  They added some
of their own ideas as well.  The four-row keyboard for Baudot is popular
in Europe.  I guess it's supposed to be easier for a typewriter-trained
typist to use.  When you press FIGS a blocking bar moves to block the
QWERT row of keys and unblock the digits on the top row.  When you press
LTRS the bar moves to block the top row and unblock the QWERT row.  And
there are some other blockings and unblockings as I recall.

The standard machine for Telex in Germany has an answerback and typically
a tape punch and reader.  The tape equipment works like that on Teletype's
Model 32/33 line.  That is, the punch uses part of the printer, so you
have to print to punch.  And the tape reader uses the keyboard distributor
so you can't send from tape and use the keyboard at the same time.
