From: S0730076@let.rug.nl (ill)

I wrote a chatbox with one of those ipx units. Pretty standard but funny
because you can send the other guy screentrashes and beeps and buzzes etc.

I dare not post it here cause Timo is gonna flame me with that standard
'don't post any binaries' file so mail me if you want it. I'll include
source from the main file here, but you can't compile it without some
other units I'm afraid.
