This is a mockup of
the device that was designed to be used by military personnel to expedite
sending messages quickly and accurately in adverse situations. For
example, a forward spotter wearing artic gloves near the north pole could
dial up a form corresponding to the situation he observes. Then the form would be
filled out in a few minutes using the dials and pushbuttons. The message would then be
transmitted to his headquarters in milliseconds by hitting the 'T'ransmit key.
