In those days, I didn't have a computer; stations on the other end of  
the radio implemented things like bulletins boards with Altairs or  
whatever they had.  The internet came along and stole all of that  
fun :)  Nowadays, one can get even get solutions to homework problems  
without having to decode the gibberish caused by a teletype machine  
incorrectly being in the "figures" state instead of the "letters"  
state. (The machines were only 5 bits; a static crash at the wrong  
moment could create amusing text.)
