Quoted from Bugsy:
I am planning on buying an NVRAM for my game, but not sure which chip type to go with. I obviously know that NGG is a WPC-95 game, but on Pinitech's website, it says those type games "could use either a 62256 SRAM or 6264 SRAM". I have done other Williams games before and simply matched the number from the existing RAM on the game with the replacement I needed.
However, on my Gofers, the existing chip doesn't seem to list one or the other of 62256 or 6264. Anyone have an idea or recommendation for which NVRAM chip to purchase?
Your chip is a 6264 equivalent. So you can replace it with the 6264 NVRAM.
Relatively easy to figure out on the non-typical part numbers. Googling "LH5160-10L" brings up some data sheets / summaries in the first few search results. If you see 8K x 8 mentioned, that's a 6264 equivalent part.... your LH5160-10L is a 6264. If it was 32K x 8 that would be a 62256.
