| Failed Timekeeper or other SRAM Chip? I have the solution for you! |

After my Timekeeper failed and I hacked it apart to repair it, I realized that there had to be a better way. I went into my shop, and I developed a template and process to place an external button battery on top of the chip, wired to the internals, and 100% serviceable by YOU. These chips typically lack any way to test, let alone service the battery inside them, if yours has failed, you'll have to hope that a NOS Timekeeper will work, and keep working for you. How long will yours last, before you're pulling it back out and reprogramming another one? With my chip, you'll have a fully-functional Timkeeper SRAM with an off-the-shelf CR2032 LiOn battery attached to it. The battery holder will be permanently affixed to the chip via epoxy, and it will be wired to the internal circuit of the chip. Never again will you have to worry if your game code is intact and operational. With a multimeter, you'll be able to verify the chip's voltage right on the surface. This is one clean package to make your game, or router, or old SPARC UNIX box keep rolling. If the battery is dying or seems old enough to replace, via the same test points, users can apply 3.3 volts and keep the chip alive while they replace the battery! Remember, even a temporary loss of that voltage and the code will be lost - these chips do not receive power to service the internal part of their clock circuit from your CPU or game power supplies! The battery is a MUST. My initial run will include: * ST's M48t59Y chips and their sub-varieties * Dallas 1225Y and other similar Dallas chips in this class * Custom ICs on a limited basis (PM me for details) The background around how I got here is in a thread about a Konami Silent Scope, if you're interested, found here - http://forum.arcadecontrols.com/index.php/topic,130544.msg1486270.html#msg1486270 I plan to market these chips for $50 each. I can offer to program them as well, on a case by case basis, provided we don't violate anyone's intellectual property. Please PM me if you're interested! |

Hi! I'm new to the site and it doesn't want to allow me to pm you about the timekeeper chip. Maybe after making a post it will allow it. If you read this and can pm me I'd appreciate learning more about how you can help me get a SilentScope2 running again, thanks! |

Welcome aboard, Canadiangamer. ;D Your PMs should be enabled now. :cheers: Scott |

:applaud: Thank-you kind sir! |

a ready to go option is actually a really good idea. The silent scope was a lost cause (was unable to program the chip for re-insertion to the unit) and was subsequently parted out. some of the konami machines include a dump in a rom chip to reprogram the RTC chips, but this unit lacked that chip. (likely intentionally as a kind of suicide battery) in any case, since my post, I've too been hacking apart failed chips and adding a 2032 battery holder to them as you mention. it's quite labor intensive and you have to do it just so, otherwise you end up killing your chip. I use these chips in older NSM CD jukeboxes... and right about now is when they are starting to fail (about 15-20 years which really in the scheme of things is not bad considering) |
