         [v2.0] Changed internal variable relating to timeleft.

                Added support for non-standard IRQ numbers (other than
                IRQ3/IRQ4). See docs for implementation.

         [v1.9] Congratulations message was overwriting previous screen
                data. Fixed.

                Added a display of the number of cards remaining in the deck.

                Changed the tableau display (card color, shape, etc)

         [v1.8] When presented with the "Press ENTER or E to exit" message,
                pressing E caused another "Press ENTER to continue" message
                to appear. Eliminated the secind "Press ENTER... " message
                after you press an E to exit.

                When using DORINFOx.DEF, the door would stop at the start 
                of the game and require a key press to continue.

                When using DORINFOx.DEF, the BBS NAME was not being picked
                up from the configuration file and was not picking up the 
                correct NODE number from the configuration file.

03/10/91 
         [v1.7] Several problems related to the use of DORINFOx.DEF
                were corrected.

02/23/91
         [v1.6] Internal changes to speed up the program.

                Will now test for maximum games reached BEFORE asking 
                if you want to play another game.

                Corrected "hung system" when responding to a
                "Press ENTER to continue, E to end.

         [v1.3] "Illegal Function Call" error msg was being generated when
                the Time Remaining value was greater than 999. Seems some
                Sysops like to give them large values. Fixed

01/02/91
         [v1.2] In unregistered versions program would produce a "Bad
                file name or number..." error msg when leaving the game.
