20 column I/O for remote terminal

[Joseph R. Mann]

 Greetings,

    I have a friend that I am trying to enlighten about the 
greatness of unix.  Unfortunately the only thing he has to
use as a terminal, is a Vic-20, running Vic Term 1.

    Does anyone here have a good way to shrink the screen
length to 20 characters or less, for normal I/O?    I tried
the 'pr' utility, but it wants to chop everything off after
20 characters. 

  Any help will be greatly appreciated. (Thanks in advance)
