That's the distinction I've been trying to point out.
And for what it's worth ONE of the acceptable modes in the ARRY RTTY 
Roundup
is ASCII (which I assume is running at 110 baud.)
So, yes, you CAN run a model 33. Just not as a "dumb terminal" on a KAM 
decoding
5-level Baudot at 60 WPM.

A terminal unit just converts the raw data from tones to a keyed loop.
All the distortion and speed errors (i.e 61 WPM vs 60 WPM) are present 
and the
machine decodes that into printed test (or punched tape).

For the pedantic, A CV-89 is a converter for RATT.
A HAL ST-6000 is a terminal unit for RTTY.
Both are raw data in, raw data out. The connected machine, Teletype, 
Lorenz, Mite,
Kleinschmidt or Creed is what does the decoding of the raw data into 
print (or tape.)

As to the "transistors in a Model 32" They are STILL only passing raw 
data. The machine
itself mechanically decodes the raw data and turns it into printing on 
paper or punched
paper tape.

The CV-89 and the Twin City TU use vacuum tubes.
The HAL ST-6, ST-6000 and the Dovetrons are solid state.
With the exception of the Dovetron running in the conversion mode, they 
are all raw
data in, raw data out and the machine connected does the decoding to 
print or tape.
