The _PDP-7/9 Dice Playing Program_ the player can place bets in an attempt to
increase his amount of virtual dollars. The player wins if he/she can earn
more than 9999 dollars. After each bet two dice are rolled. The sum of the two
dice must be rolled again on a successive roll to get a payout, but once a
seven is rolled the player loses his bet. If the initial roll is a seven or an
eleven the player immediately wins. If it’s a two the player immediately
loses.
