I've been trying to get my battery backed ram working in my Tron without luck. Installed it without any mods and I found that the game would randomly reset (switching back to 6116 worked fine). I then played around with tying vbatt to +5v - both before and after the inline resistor. In both cases I either get RAM B02 error or garbage. Now if I try just the nvram alone I'm still getting garbage so I'm not sure if it's now bad for some reason or if it's just temperamental, whether it boots ok and resets later or boots to garbage.
Any ideas what I'm doing wrong or if my chip is bad? I'm currently back to the 6116 and everything's working fine, so no other issues in the system.
