I believe most people who are doing amateur RTTY are using 5-bit, 45.45 baud
machines such as the model 15 and 28 and others, rather than the 110 baud, 7
bit machines like the ASR33, simply because the vast majority of amateur RTTY
is at 45.45 baud, 5 bit Baudot code. Of course, the majority of amateur RTTY
operators are not using Teletype machines at all, but rather computers. 
This isn't to say that you couldn't convert between the ASR33's 110 baud, 7 bit
code and the usual amateur RTTY code, but it might be easier to look for a
machine that speaks it natively.
