I discussed that a couple of month ago, if you make a TVison port using Curses 
you'll need a mainframe to get a relative good speed in the screen. 
On the other hand you can rewrite TVision to be more efficient and eat more CPU 
instead of making so much screen output, but that's a real nightmare. Do you 
have any idea of how complex are the output routine for this kind of programs?
