********** ARROW BINGO **********
Arrow Bingo is a skill game with the ever-popular Bingo theme. Columns are moved up and down
to line up the winning numbers with the time clock running... (from the flyer).
The code has a timer that takes a couple of minutes to boot into the game.
This is completely normal and expected.
************ SYMBOLS ************
INTRODUCTION
Symbols is a video skill game displaying a large red bordered box with a white grid of 5 rows
across and 5 columns of symbols down. The object of the game is to line up the winning symbols
either horizontally or diagonally in the shortest amount of time with the least amount of moves.
The winning symbols are selected at random at the start of the game and displayed with a
distinctive yellow color surrounding that symbol in each column.
HOW TO PLAY THE GAME:
The player must first insert coins to obtain points to play the game. Once points are on the
screen the player may then press the play button one time for each point available up to the
coin multiplier limit (except when lockouts are in effect) at which time the game will auto
start. If the player wants to start before the coin max, he may press the start button to
initiate play. At the start of the game arrows are displayed at the top of columns to show the
direction to move that column in order to get the winning symbol on screen, in the event that
particular winning symbol is already on screen, that symbol will appear at the top of the
column instead of the arrow. When the player has all the winning symbols on the screen an
alignment of winning symbols, either horizontally or diagonally, should be done with the least
amount of moves in the shortest amount of time. In the event the lockout mode is engaged the
game will accept coins up to the lockout limit and will then auto start.
The game has two different win modes defined as follows. If an alignment is obtained in 13
moves or less, the player will be awarded points defined by the award tables. If alignment
is obtained from 14 to 32, moves stars will then be awarded for the amount of moves as
defined by the awards table. A bonus of 3 stars will be awarded if game is completed in 3
seconds or less and 100 stars equals 1 point.
Time is also an element in this game. When the game is started the player has a specific
amount of time to complete the game, also the arrows have a time limit. These time factors
are variable and may be adjusted in the setup mode. The game also show how the game may be
played.
ADJUSTABLE FEATURES:
Symbols has been designed for the convenience of the operator. The game is very flexible,
easy to use and can be custom tailored for each location by a menu driven setup mode.
To enter the setup mode, locate 2 small switches, with black rubber tops, on the logic board
labeled SW1 and SW2. First depress and hold SW2 and momentarily depress SW1, until the MAIN
MENU display appears on the screen. At this point you should see a menu that looks as follows:
MAIN MENU
-----------
ACCOUNTING MODE
POINTS SETUP
PLAY TIME SETUP
BUSINESS NAME SETUP
SYSTEM TESTS
GAME STATS
When you have this display on the screen you are in the setup mode. You will note a different
color band around one of the selections. This band indicates which module is to be selected
to enter that particular mode. This band may be moved by depressing either the first column
up or down arrow on your front panel. To enter a particular mode just depress the PLAY button
on your front panel. To exit a mode just depress the START button on your front panel. To
adjust an entry in one of the modules use the second up or down arrow on your front panel. Now
lets go through each module so you know how to customize your game for a particular location.
Let's get into the first module on the menu which is the ACCOUNTING MODE. Remember to depress
the PLAY button on your front panel and presto, we are in the accounting mode. The display you
see should look something like this:
ACCOUNTING MODE
----------------
COINS IN: 0000
POINTS AWARDED: 0000
PLAYS TO DATE: 0000
STRUNG COINS: 0000
STARS AWARDED: 0000
GAMES PLAYED: 0000
To clear the accounting back to zero, use the second arrow down button on your front panel for
each item and use your first arrow up or down to move to each item.
To enter POINTS SETUP, move the shaded color bar to POINTS SETUP and depress the PLAY button on
your front panel. You should have a display that looks as follows:
POINTS MENU
--------------
POINTS SETUP
POINTS MULTIPLIER
Select the POINTS SETUP by depressing the PLAY button on your front panel and you should have
a display that looks similar to the following:

To change any of the above values, move the shaded bar by depressing the first up or down arrow
to the desired award and then change the values by depressing the second up or down arrow until
the desired value is reached. To exit, press the START button on your front panel.
To change the POINT MULTIPLIER, enter this module and use the first up or down button on your
front panel to increment or decrement this value.
To change PLAY TIME SETUP, enter this module and you may change PLAY TIME or ARROW TIME (the
amount of time arrows are allowed to stay on screen during play). To enable the lockout mode, you
may set the lockout number to 1 or 2 or 3 or 4 and 0 if no lockout is desired. To disable the
STARS set the STAR MODE to OFF. To adjust the UP AWARDS set to ON for more upper awards and to
OFF for less upper awards table wins.
The default name used in BUSINESS NAME SETUP is "THE MANAGEMENT". If you want to put a location
name in the attract mode, enter the business name setup and use the second up and down arrows to
select from the alphabet. In the event you make a mistake you can backup by selecting the first
up arrow. When you are finished with your message just exit by pressing START button and the
message will automatically center when you exit.
SYSTEM TESTS
The SYSTEM TESTS mode allows you to test the ROM, RAM, CTC, MONITOR, and perform I/O tests.
The I/O tests allow you to check each front panel switch and the coins in switch individually.
To exit from the I/O mode, you have to press the SW1 reset switch on the logic board.
GAME STATS
The GAME STATS mode indicates the number of wins for each award in the awards tables. To clear
these back to zero depress the second arrow down button on your front panel.

DRIVER UPDATES:
[2010-10-10]
- Initial release.
- Almost accurate memory map.
- Decoded graphics.
- Decoded the bipolar PROM.
- Detected a CRTC (MC6845 type) reversing the code.
- Guessed the CRTC clock to get proper values.
- Hooked the AY-3-8910.
- Added games notes.
- Added technical notes.
TODO:
- Improve the memory map.
- Reverse the IO port R/W.
- PIO / CTC / daisy-chain interrupts.
- Inputs
* avtbingo, avtsym14 will accept coins. PIO-1 is programmed to cause an interrupt
when coin1 is pressed (port02).
* avtnfl, you need to set it up before it can accept coins. However, it is random if it works
after doing that. If you want to try, press 7 to enter setup, press 6 to select the adjustments
screen, choose items with 2 and adjust them with 4. Press 6 until you exit. If you're lucky enough
to get it to work, 2 will enter coins, 3 will tilt (don't do that!), 6 is Draft, 1,2,4 (at least)
will remove cards. Don't know what the aim of the game is though.
* avtsym25 has mismatched program roms so cannot work.
