wpeej Posted May 29, 2019 Share Posted May 29, 2019 I have a late 90’s Royal Vendor 550 Coke machine with a bad timekeeper RAM (battery wont hold a charge). I’ve seen online how to mod the chip and install a new battery, but can other newer chips be installed? It currently has a M48T18-100PCI. Thanks!

AZVendor Posted May 31, 2019 Share Posted May 31, 2019 Timekeepers don't need to be "modded." Get one at Mouser Electronics. Link to comment Share on other sites More sharing options...
orsd Posted June 1, 2019 Share Posted June 1, 2019 Yup. Part is literally 20 bucks, not worth the time and effort golpher with it. https://www.mouser.com/ProductDetail/STMicroelectronics/M48T18-100PC1?qs=eb%2FRSZx1fMunpGzmmpiWeQ%3D%3D Link to comment Share on other sites More sharing options...
wpeej Posted June 3, 2019 Author Share Posted June 3, 2019 I ended up buying one from China...$7 shipped and works great. If it fails again I’ll go with the mouser product. Thanks for the feedback! Link to comment Share on other sites More sharing options...
