Jack,

TWX cut to dial with ALL 5 level machines in August of 1962.  The 
Navy TT-242 year is 1961... the machine that pre-dates the 32. 
Production of the 32 about the time of the Cuban missile crisis; and 
the 33 did not come until a little later about 1964/6.  ASCII was 
first standardized in 1963.   Finalized in 1967. The very first 33s 
had the ALT MODE non-parity keyboard... but not for long before the 
ESCAPE key and even parity.  So it depends on exactly what time the 
movie is depicting.

Jim Haynes and or Ben Stephens should the dates know for sure.
