Eliminate your batteries and avoid damage to your game!
This 28 pin Dip NVRAM is plug and play and requires no soldering for most games.
Note about games with a clock / Midnight Madness etc: This device will retain the RAM data when the machine is powered off, and will come back to the same values when the machine is powered back on. Games with real-time clocks will not advance while the machine is powered off. This is not specific to this device, but NVRAM’s in general. You will still be able to utilize Midnight Madness modes, etc, but you will need to manually set the game clock to the desired time each time.
Avoid damage to your board! Remove those batteries immediately before they leak all over your board! This NVRAM will allow your game to run without batteries being installed.
If you already have acid on your board…don’t just get rid of batteries and leave it…it must be neutralized or will continue to spread! Please see http://pinwiki.com/wiki/index.php?title=Bally/Stern#Repairing_Alkaline_Damage

***Below systems are NOT “plug and play” and recommended only for people with advanced soldering knowledge. The older boards have very delicate solder pads and traces that can easily be damaged by improper soldering and/or overheating. All board modifications are always at your own risk!!!***
Games that require unsoldering/soldering the chip (Installing a 28 Pin socket is recommended:
WPC / WPC95 (Chip Location U8)*:
Attack from Mars
Bram Stokers Dracule
Bride of Pinbot
Creature from the Black Lagoon
Indiana Jones 93
No Good Gophers
Start Trek (1993)
Tales of the Arabian Nights

Games that require unsoldering/soldering the chip and jumper(s) (Installing a 28 Pin socket is recommended):
**Williams System 11B (Chip Location U25):
Black Knight 2k
Elvira and the Party Monsters
Swords of Fury
**Williams System 11C (Chip Location U25):
Bugs Bunny Birthday Ball
***Williams System 11C (Chip Location U25):
* Not all WPCs are directly configured with 6264s. The WPC MPU can be rejumpered to use a 62256, and some games shipped with them.
To convert a WPC-89 MPU that is already set up with a 62256, you will need to add a resistor @ R93 (1.5k ohm), and remove jumper W3. Failure to do this may keep the MPU from booting once it is installed, but others have said not always necessary. Your mileage may vary.
** Williams System 11B/11C have a 24 pin 6116 RAM hard soldered in from the factory at location U25, and need a 28 Pin socket installed. To use a 6264 type NVRAM, you must also change the jumpers: W5 removed, and W6 installed.
***System 11 and System 11a CAN NOT be changed and ONLY support a 6116 style RAM, so this chip is not compatible with those machines.
