Overview \ :
+-----------`---------------------------------------------------------------.
:
This is a board that replaces the daughterboard on a ms pacman PCB and adds :
both high score support and a top ten list to the attract mode. All dip :
switch settings are moved to nvram and are accessed through a menu. Added :
features include 2 new difficulty levels, cheat mode, speedup mode, :
screensaver and start on any level. Multiple mazes are included and :
accessed using dip switches on the board. Each maze has it's own top ten :
list and the fruit paths work on all mazes. :
:
The board does rom banking in the menu to get different mazes. The title of :
the rom bank in use is displayed at the top of the screen, you just press :
right or left to get to the next maze. I will provide a build kit so you :
can put whatever maze hacks you want in your rom image. The board also has :
connection points for banking the graphics rom in case I decide to release :
an original game with the board as well. :
:
There are two different 'styles' of High-Score boards - plug-in and ribbon :
cable. The Plugin style replaces your z80, you use your z80 in this board :
instead. Note: the Plugin board will *not* clear the sync bus card. Unless :
you have the original NAMCO chip or the new tiny style replacement, you :
will need the Ribbon Cable style. The Ribbon Cable style plugs into your :
ribbon cable in place of the Ms Pac daughterboard. :
:
:
+--------------------------. :
Installation Instructions \ :
+----------------------------`----------------------------------------------.
:
Program Board :
------------- :
Remove the four EPROMs in row 6. If you have to remove the syncbus card to :
get to 6e make sure you plug it back in the same way. Remove the z80 from :
the ms pac auxillary board and place it in my board in the socket near :
the center. There should be a notch or dot to indicate pin 1 on the chip. :
Then plug my board into the ribbon cable in place of the ms pac auxiliary :
board. Turn all dips off. :
:
Graphics Expansion Board (if supplied with your kit) :
------------------------ :
Carefully remove your 5e and 5f roms - pay attention to the orientation. :
The small graphics board is plugged into a socket to protect the pins. :
Remove the socket and plug the graphics board into location 5e. The notch :
on the EPROM is in the same direction as the original 5e EPROM was. :
:
:
+--------------. :
Configuration \ :
+----------------`----------------------------------------------------------.
:
Once installed, the High score save kit should be cleared and configured :
to your needs. To do this: :
:
1. Power off game :
2. Set all DIP 1-8 to OFF :
3. Set DIP #6 to ON :
4. Power up game :
:
You should now see a MENU that reads. :

:
There should be a RED power pellet to the left of 'Next Maze'. You move :
this red power pellet using the joystick up/down and change the selection :
by moving the joystick LEFT/RIGHT. (RIGHT is choose, LEFT is to go back :
in the choice menu, Pressing Player 1 Start will cause the LEFT/RIGHT :
choice to jump by 8 or 10 increments instead of 1, i.e. a fast forward :
button.) :
:
Move down to CLEAR & move joystick LEFT. This clears the NVRAM for this :
game only & now you may set up the game as you like. :
:
:
+-----------------------. :
Features and Functions \ :
+-------------------------`-------------------------------------------------.
:
NEXT GAME - this allows you to chose from the various installed mazes, Ms :
Pac, Ms Pac Plus, Ms Pac No Exit, etc. This will be your default game upon :
power up. :
:
CHEAT - ON/OFF - this turns on the cheat mode. When on you may press Player :
1 Start to become invincible. Pressing Player 2 Start will be change your :
speed to Fast if you are in normal mode or to slow if you are playing a :
fast mode game. :
:
SPEED - NORMAL/FAST - this sets the default speed of the game to normal or :
fast. :
:
1 COIN 1 CREDIT - allows you to alter coins per credit or choose FREE PLAY. :
Freeplay now has an attract mode. There is no on/off setting, if you are in :
freeplay mode, it works exactly like 1 coin/1 credit. :
:
BONUS 20K - allows you to set the number of points required to earn an :
extra Pac-Man. Note: a hidden feature is enabled by setting bonus to 28K, :
2 Player simultaneous Pac-Man, 2nd player is able to control the RED Ghost :
(Speedy), or the computer will control it if no one plays the 2nd Joystick. :
:
MS PAC-MEN - 1 to 256 allows you to set the number of Pac-Man given per :
credit to start a game. :
:
UPRIGHT - UPRIGHT/COCKTAIL allows you to set the mode of the cabinet. :
:
SCRN SVR - ON/OFF is a screen saver feature that prevents a static screen :
burn in on your monitor. Screensaver runs a special entirely black screen :
with a ghost moving across it every few seconds. The setting for :
screensaver is the number of attract mode cycles before it activates. Off :
or 1 to 255. Any stick movement, coin drop or button will take it out of :
screensaver and return it to attract mode, or start screen in the case of :
a coin drop. :
:
DIFFICULTY - NORM/HARD/XDIF/MAX - sets the game difficulty level that :
controls the attack patterns and time of ghost. NORM is the normal setting, :
HARD is the original hard setting. XDIF is extra difficult & becomes much :
harder faster than on factory available settings. MAX is maximum :
difficulty, the first level is as hard as it gets. :
:
STARTING LVL - 1 to 256 - set the starting level of the game if you like. :
NOTE: For Ms pacman the split screen "feature at the last level" and all :
the other kill screens have been "fixed" and is playable as any normal :
screen, the game will also roll over to screen 1 again. However the :
difficulty remains at maximum. It was necessary to fix the kill screen :
because the memory trashing bug at level 134 also trashes the high score :
table. :
:
LOCKED - LOCKED/HOME allows you to choose between commercial use and HOME :
use. HOME use allows you to access the setup menu using Joystick LEFT and :
Player 1 Start & Player 2 Start simultaneously. If freeplay is on, be sure :
to move left before you push the buttons. (Note: this is a global setting :
that applies to all games, you can not configure some games for Home and :
some for Locked). :
:
CLEAR - YES is to ERASE *ONLY* the high score saves in the NVRAM for the :
particular game you are in, it will not effect the other games settings or :
hi scores. :
:
EXIT - will return you to game over mode but only if DIPSWITCH #6 is OFF, :
otherwise you will just see this menu again. :
:
:
+-------------. :
Dip Switches \ :
+---------------`-----------------------------------------------------------.
:
The test button works like dip 6, but only during the top ten list. At all :
other times, the test button works like normal and resets your machine. If :
you don't want to use dip 6 during the initial configuration, you can start :
the game and wait for the attract mode to run through and the top ten list :
to start. :
:
Dip 8 is still video freeze. :
:
Dip 7 is still the rack test. :
:
Dip 6 allows access to the menu. :
:
Dip 5 'on' puts the game in guest mode. In guest mode, you can get into the :
menu but not change dip settings. Guest overrides home/locked settings. :
:
Dip 4 'on' puts the game in Tournament mode. In this mode, only specific :
settings will count towards the high score (3 lives, cheat off, etc.). If :
the word Tourn is in red then your settings are not correct and no scores :
will count. :
:
Dip 3 'on' allows fast games to count towards high scores. :
:
:
+-------------. :
Reset Switch \ :
+---------------`-----------------------------------------------------------.
:
Although most high score kits now ship with a wire to connect a reset :
switch, some early boards did not have this feature. If you want to add a :
reset switch, you simply cut one trace, add 2 resistors and a jumper wire. :
Referencing the picture on my web site, cut the trace with the red X. I :
used a 10k resister where it is marked "P" and a 50 ohm resistor where it's :
marked "F". You then run a wire from either resistor (marked 1) to the :
reset on the z80, (marked 2). I attached a wire to the hole at W and when :
that wire is grounded, the board resets. :
