Here's some details (as I remember it):
Each person is represented by an ASCII character (I believe the @ symbol was one of them). On your turn, you had to move to one of the available stocks. Once there, you could either buy or sell stock, but only one action was allowed. Then the other person got their turn, and the market "adjusted" by some algorithm I'm sure is now laughable

Anyway, if this strikes a chord with anyone, and you know where I could download/buy a copy, you're my hero...
