  So the model-33 wasn't ASCII?  
 Nope; it was 5-bit Baudot (technically ITA2).  Upper case only, and there 
 were codes to shift between letters and figures.  Grep thee the net for 
 "ASR33". 
I've used an ASR33 with an PDP-8-E, an ASR33 with an opto coupler
to some tymeshare services and an ASR35 as a console to an PDP-8-I
but theses where all ASCII.  According to wikipedia "A companion
Model 32 used the more established five-level Baudot code."

And have a look at the picture of Ken & ennis with two 33's
<http://cm.bell-labs.com/cm/cs/who/dmr/picture.html> and comments
from dmr. Note te ASCII keyboard.
