Most (all?) Teletypes are pretty awful, but maybe we
ought to be a little
forgiving, being mechanical.
When we were in high school, Frank McConnell could type at a pretty
impressive rate on an ASR33 using (if I recall correctly) just his
thumbs and index fingers. He seemed to be able to duplicate the data
rate of the incoming characters. The host system would send down a
prompt and he would key a command and there was no noticeable pause
or break in rhythm between the two. Impressed me anyways...
