6264 NVRAM Module

No more batteries!

This is a Nonvolatile RAM (NVRAM) Replacement for the 6264 RAM used in pinball / arcade machines. 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. Absolutely no batteries are needed to retain your high scores or game settings, you can remove them from your game. Machine pin headers are used in this module which are very durable and won't damage your socket at all.

Please note that on some games this will require removal of the existing RAM soldered to the board & installation of a 28-pin DIP socket (now included!!). Please see the compatibility list below for more info.

WHY REPLACE YOUR EXISTING RAM WITH NVRAM?
Unfortunately battery corrosion damage is much too common in games that used alkaline batteries for powering the RAM when the pinball machine is off. Many people have reported that even new batteries from major brands can sometimes leak after a year or two for no apparent reason. The corrosive alkaline can leak or wick into the board and over time will destroy the copper traces on the board and any ICs it comes in contact with. Don't let this happen to your game!


COMPATIBILITY
First of all, to figure out your manufacturer / boardset the easiest way is to check out the Switch Matrix Database and select your game. The manufacturer/boardset will be next to the name of the game. You could also consult IPDB.org search for this info. That will help identify what RAM you need and you can then check out the details specific to your board below.

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 cannot be guaranteed to work in applications not listed & 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. Note that 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. If you find this nvram compatibile with other devices, please let us know.

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

Boards listed as "*requires socket installation" above (mostly just WILLIAMS mpus) will likely 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. Williams System 11 and WPC boards have delicate traces and without proper equipment or technique you may end up causing damage to your board. Please be aware of this before purchasing the nvram module and understand the risks involved in attempting to upgrade your board.

Any attempt to modify your board is AT YOUR OWN RISK. If you aren't comfortable with performing the modifications (should your board require any for nvram installation), please seek professional installation or use a remote battery pack instead.

NVRAM is shipped in anti-static foam & anti-static bag inside a small USPS First Class Mail box. Installation instructions are included.
