Description

6264 NVRAM Module

 

No More Batteries!

This is a premium quality Battery Eliminator / NVRAM for the 6264 RAM used in pinball & arcade machines. Once installed, you can remove the batteries from your machine and your high scores / settings will be saved for many years to come!

Replaces a 6264, 6064, 2064 or compatible pinout "8k x 8" SRAM. These modules use CYPRESS F-RAM nvram ICs rated at 151-year data retention & 100 trillion reads/writes. Module installs easily into any IC socket.

Please note some games may require removal of the existing RAM and installation of a 28-pin IC socket (included) to use this nvram module.
See the COMPATIBILITY LIST below for more info.

 

WHY REPLACE YOUR EXISTING RAM WITH NVRAM?
Batteries leak. Even brand new batteries from major brands have leaked a year or two later for no apparent reason and cause hundreds of dollars in repairs or replacement of boards and components affected. Upgrading to NVRAM will save you time, money and any future worry of battery damage. It's one of the best mods you can do to your games.


COMPATIBILITY LIST
For pinball machines, download the "Pinball NVRAM Game List" PDF document to find what type of NVRAM you need for each game you'd like to upgrade. This will also help identify what games are plug-and-play and which require soldering for installation.

Additionally, check out the compatibility chart below for board diagrams showing the location of the RAM on the board, difficulty of the installation & any other usage/installation notes.

 

BOARDSET DIFFICULTY RAM LOCATION NOTES
 
DATA EAST EASY
(see notes)
5D
(see picture)
Plug-and-Play on all Data East games except "Laser War". If you are installing nvram in Laser War you may have a "Data East System 1" MPU that only works with the 6116 NVRAM Module.
 
SEGA WHITESTAR EASY
(see notes)
U212
(see picture)
Plug-and-Play on all Whitestar games. If current jumper setting is for 32k RAM (ie. 62256 RAM from the factory installed) it's *technically* not a bad idea to change the jumper for the memory type to the 8k setting, but should work without this change.

Jumpers block "JP1" is directly below the RAM chip on many of these boards, but may be a physical jumper on some boards instead of a movable shunt/jumper block.

 
STERN WHITESTAR EASY
(see notes)
U212
(see picture)
Plug-and-Play on all Whitestar games. If current jumper setting is for 32k RAM (ie. 62256 RAM from the factory installed) it's *technically* not a bad idea to change the jumper for the memory type to the 8k setting, but should work without this change.

Jumpers block "JP1" is directly below the RAM chip on many of these boards, but may be a physical jumper on some boards instead of a movable shunt/jumper block.

*Note: Sharkey's Shootout requires a 62256 NVRAM Module to be used.

 
WILLIAMS SYSTEM 11 MODERATE U25
(see picture)
NOT PLUG-AND-PLAY. Requires removal of existing RAM & installation of a socket! If no one has replaced the RAM on your board, it's likely the existing RAM is a 6116 -- easily verified if the chip at U25 is 24-pin (6116 RAM) instead of 28-pin (6264 RAM). Since most System 11's appear to have had 6116 RAM installed from the factory, you'll likely want to go with the 6116 NVRAM Module to avoid having to make any jumper changes to the MPU board.

Williams System 11 games did not have their RAM socketed from the factory. Unless someone has replaced the RAM and installed a socket, you will need to remove the existing RAM IC and install a 28-pin socket. Additionally there would be a jumper change if the old RAM is a 6116. See note above. THE VERY FIRST SYSTEM 11 BOARDS (System 11, System 11A) WILL *ONLY* WORK WITH 6116 NVRAM.

Jumper Settings (System 11B/11C boards):
Jumper W5 installed (W6 removed) = 6116 NVRAM
Jumper W6 installed (W5 removed) = 6264 NVRAM

 
WILLIAMS WPC HARD U8
(pictures below)

WPC-89
Includes WPC-Alpha, WPC-Dot, WPC-Flip1, WPC-Flip2

WPC-S

WPC-95

NOT PLUG-AND-PLAY. Requires removal of existing RAM & installation of a socket! Williams WPC games did not have their RAM socketed from the factory. Unless someone has replaced the RAM and installed a socket, you will need to remove the existing RAM IC and install a 28-pin socket. Rated higher difficulty due to thin traces on Williams WPC MPUs. Additionally there may be a jumper change required.

Note: Games could use either a 62256 SRAM or 6264 SRAM. If your game is currently using a 6264 SRAM at U8 no changes are needed. If your game currently has a 62256 in it, you may want to consider just purchasing the 62256 NVRAM Module to avoid having to make any jumper changes.

Jumper Settings:
6264 = install R93 (1.5k ohm resistor) and remove jumper W3
*Only needed if your existing ram IS NOT a 6264

Real-time clock will not function correctly on any games that utilized the clock for Midnight Madness Mode or other special time-sensitive modes. Midnight Madness Mode will not start at the correct time on Dirty Harry, Johnny Mnemonic, WHO Dunnit, Theatre of Magic, Congo, Junk Yard or NBA Fastbreak. In addition to this music on Creature From the Black Lagoon based on different dates will be affected. Twilight Zone's clock on the playfield will not show the correct time. There may be other games affected in addition to those listed here. Basically these functions will still work, but will not be based on the correct time since with nvram installed the real-time clock does not get updated when the machine is powered off.

 

*NOTE: EACH MODULE NOW INCLUDES A FREE 28-PIN IC SOCKET!


Your current RAM might not be labeled as a "6264" or "62256" -- some RAM manufacturers used different numbering on their RAM like "LH5164AH-10L" for a 6264. The easiest thing to do is to write down the numbers on the RAM IC (located via the pictures above) and Google it to see if it's an 2K SRAM (6116), 8K SRAM (6264) or 32K SRAM (62256). If in doubt, please contact us with a picture of your RAM or the number on the chip and we'll help you out.

COMPATIBILITY WITH OTHER DEVICES
This memory may also work in other applications where a 6264 RAM is used, but should not replace memory in critical circuits without proper testing. The 6264 module has been used to replace the Dallas DS1225Y Nonvolatile SRAM in Tektronix Oscilloscopes. The F-RAM chips latch each address on the falling edge of the /CE (chip enable) line, so in the hardware being upgraded the /CE line must be toggled for every read/write (not tied to GND). The chip enable circuit can be verified via schematic, but the toggling of the chip enable line on every read/write would need to be verified via logic analyzer.

 

--- NOTE ON BOARDS REQUIRING SOCKET INSTALLATION ---

Boards listed as "*requires socket installation" above (mostly just WILLIAMS mpus) will require the existing SRAM to be desoldered/removed from the board and a socket installed in its place. If you do not have proper equipment or experience to desolder ICs and install a socket, this mod may not be for you as some of these boards have delicate traces. Please be aware of this before purchasing the nvram module.

Any attempt to modify your board is AT YOUR OWN RISK.
If you're upgrading a board that requires modifications and don't feel you have the right equipment or technique, please seek professional installation or use a remote battery pack instead.

NVRAM is shipped in anti-static foam & anti-static bag. Installation PDF instructions are located here
