[GreenKeys] Teletype Model 242 (?)

[Duncan Brown]

Don,

I would like to see a picture, too!

"Model 242" seemed like a very high number; I was about to ask if you 
meant "TT-242" since it was a military unit.  But I did a little 
research and found a document that states:

"1961 - The Model TT-242 is rejected by the Navy in favor of the MITE 
compact Teleprinter.
The TT-242 becomes the basis for the Model 32 and 33. The M32/33 
represented the marriage of
many proven designs into a totally new design, best described by the 
term "low-cost concept."
Approximately 6 years of research and development went into the Models 
242, 32, and 33. Also,
the 8-level Model 35 is derived from the 5-level M28."

(the document is "A Synopsis of Teletype Corporation History" by Don 
Robert House, as found on Baudot.net)

Have fun,

Duncan
