Does anyone by chance have the 1988 edition, red box, or close, who'd be willing to photocopy the instructions?
Sorry can't help ya.
I do have the "blue" 1981 edition of the game with the "Rules of Play" -
it's my understanding the game changed very little over the years.
If no one comes up with your game - I'll be happy to scan and post the "rules" on our forum.
