Hi everyone, I recently installed an anyPin DMD NVRAM in my WMS IJ without incident, it fired up first try. Today I tried to install one in my ST:TNG. The difference is that the MPU board is a Rottendog. I was happy to see that there was already a chip socket... Easy right. However when I install the chip, the pin won't boot. There is a tone but no display and no beginning cycle / sequence. I killed power and I re-seated the chip... no change. So I put the original 62256 ram chip back in and reattached the batteries... Back to normal. SO - Do I need to buy a specific 62256 NVRAM chip or should the anyPin work? Could it be a bad NVRAM chip? Anybody experience this before? Any help / advise is appreciated!!!
