NVRAMs $15ea for 1, $10ea for 10+ and free ship.
Quoted from pinballkyle:Nvram is a great solution but it can have some minor, but solvable issues.
The fit of the stern socket can be quite loose for the nvram and can cause the memory to be occasionally erased due to a loose fit. This has happened on two of my sterns on location.
Technically it's plug and play but if you want it to work perfectly for years, the old socket should be desoldered and the included socket should be installed. This is what I'm doing now.
I have found the opposite. NVRAM modules (at least the ones I assemble) use round pins. These are actually a hair bigger then the standard flat stamped legs on SRAMs giving a very snug fit on Stern games.
If you go NVRAM, then take it out and put a regular SRAM back in, the original SRAM may be a loose fit.
Good quality machine pin style socket is probably ideal for NVRAM modules, but the twin leaf standard style sockets work fine too.
