I just ordered these. Going to try them in a Jurassic Park that is not keeping memory for some reason.

Quoted from dozer1:Has anyone bought these NVRAM ebay.com link
and installed them in a system 11? Here is what is confusing me a little.
U25 on the system 11 MPU uses a 24 pin RAM and these NVRAM are 28 pin. Now there are 4 extra holes on the board that were unused from the factory. Do you simply solder in a 28 pin socket and use the 28 pin NVRAM?
This post explains what to do with 24 pin RAM. This is what I am assuming.

I actually ended up swapping 3 games. Jurassic Park, Baywatch, and Lethal Weapon 3. Everything works without a hitch and verified RAM data is saved after turning off power. I did notice the legs in these are a bit flimsier than the Hyundai ICs that were originally installed so be very careful when installing these Ramtrons!
