There was a program at SEX that would generate a TTY map 
automatically of what hosts were up and down.  They were formatted to 
print out on a model 33 teletype or better yet a model  37 to fit on 
one standard piece of paper.  I remember it very distinctly and 
probably have one of the maps squirreled away somewhere.  Ask 
Ollikanen, he will remember it.

It was quite popular.  So much so that people were asked to not 
connect to it so often.  And as I said, it went away when it was no 
longer possible to fit all of the hosts on one sheet of paper.  So it 
was probably defunct by 1972 or so.

Take care,
John
