Battlezone High Score Save
Kit -- Installation Guide |
Step 0: Make sure your game is fully working
Before installing this kit, make sure your Battlezone game is fully functional.
This kit can only work in a fully functional game.
Step 1: Turn off power to the game
While it may be possible to install this kit without removing your board from its
cabinet, you will find it easier to install the kit if you do remove the board.
Pay careful attention (or label), any wire connections as you disconnect your board
so that you can correctly rehookup the game PCB afterwards. Take note of which side
of the PCB edge connector is facing the parts side of the board and which side faces
the solder side, The connectors are sometimes not keyed and can be inadvertantly
plugged in backwards - ouch! It is recommended that you label the connector faces
with something like "parts side" or "solder side".
Step 2: Locate and remove the game PCB
For Battlezone upright, the game PCB is usually attached to the left side of the
cabinet (as viewed from the front). The board may have a screw attaching the boardset
to the side of the cabinet, which will need to be removed so that the boardset can
be removed for easy access.

Step 3: Remove the 6502 CPU chip
Locate and remove the 6502 CPU chip on the boardset. Use the images below to assist
in locating it. See 6502
Chip Identification for additional information. The 6502 CPU chip is a 40 pin
(large) chip, located at M3 It is the only 40 pin chip on the boardset. Remove
the chip gently by using a flat head screwdriver to pry it out of its socket from
each end. Some of the Atari boardsets have open frame sockets which do not protect
the PCB traces. Be careful not to scratch any of the PCB traces underneath the
socket. Also be careful not to bend any of the pins. If any pins do get inadvertantly
bent, you will need to straighten them out before the next step. Needle nose pliers
work the best for this.

Step 4: Insert the 6502 CPU into the daughter card
Insert the just removed 6502 CPU chip into the empty 40 pin socket on the High Score
Save Kit. Make sure pin-1 is correctly oriented. Pin-1 is marked on the 6502 CPU
chip usually by some type of indentation or circle molded into the plastic. The
end of the chip with the marking, needs to match up with the socket on the daughter
card that also has a marking on the plastic. There should also be a small sticker
on the daughter card marking pin-1. If the 6502 chip is installed backwards
it will cause permanent damage to the 6502 chip.

Step 5: Insert the daughter card into the boardset
Insert the daughter card back into the 6502 CPU socket on the boardset where the
6502 CPU chip was originally removed from. Again, make sure pin-1 of the 6502/daughter
card is oriented to correctly match pin-1 on the boardset. Use the photos as a guide.
Step 6: Double check your work
Review the steps and double check that 6502 CPU is properly installed into the daughter
card with no bent pins and that it is correctly oriented for pin-1. And that the
daughter card is also installed snug into the 6052 CPU socket at M3 with
pin-1 matched up. REPEAT: If any of these devices are installed backwards it
will cause permanent damage to the devices!
Step 7: Powerup and game and enjoy!
Reinstall your board into the cabinet, hookup the edge connector with the original
orientation and then powerup your game.
If the game does not come up, turn power off immediately, double check your work,
and read over the trouble
shooting section.
As a side note, if you want, you can also remove the old code eproms. These are
located at the edge of the board near the 6502 CPU location. See
code eprom picture.
Easy to clear out the high scores when desired. Simply put the game into selftest
(using the cabinet selftest switch). Once in selftest mode, press (and hold)
the start button and the fire button. The screen will imediately show "ERASED"
indicating the high scores have been cleared out. This is a similar procedure used
by other atari games. See
Clearing High Score table
for detailed directions.
