3.  VIP BINGO

VIP BINGO automatically calls and verifies BINGO numbers.  The computer selects
numbers randomly and displays the last three numbers drawn.  After a player calls
"BINGO", the computer will check the player's numbers against a list stored in its
memory.  The computer adds the numbers checked to give the player a score for that
round of play.

There are two modes for drawing numbers.  Using the manual mode, the operator must
press a key to obtain a new number.  Using the automatic mode, the computer draws
numbers every twelve seconds until halted by the operator.  Using a third mode, verify,
the operator enters numbers on the keyboard for the computer to check against the
list of numbers called.

How to play VIP Bingo

1. Load the CHIP-8 interpreter at 0000-01FF and the game starting at 0200.

2. Turn RUN switch on.

3. Key "A" starts calling numbers in the manual mode.  Press key "A" for every new
   number.  New numbers appear at the bottom of the display and are rolled upward.

4. Key "B" starts calling the numbers in the automatic mode.  New numbers appear every
   twelves seconds until all numbers are called.  You can press key "A" to enter manual
   mode, or key "C" to stop calling numbers.

5. Key "C" starts the verify mode.  Enter two digits for each number making up a winning
   BINGO card.  (Note: press 01 for B-1, 02 for B2, 75 for O-75, etc.)  If the number
   was called, "OK" will show; if it was not called, "NO" will show.  If all five numbers
   are OK, press key "F" to display the score for the numbers entered.  The score will
   be displayed followed by "PT" (point total).  You do not have to enter any number for
   "FREE".  If one of the numbers verified was not called, you can resume calling numbers
   as in Step 3 or 4.  You may also press key "C" to restart verify if you make a mistake
   entering a number.
