Hi. A few months ago I repaired Mac Classic. Today I have a SE model. Now I have a problem with PRAM.

I installed a new Lithium battery, but mac still can't save parameters to PRAM (eg. speed of mouse). Where is PRAM chip? Or what's going wrong?

OK. I found it. The PRAM is in RTC chip on board. But I can't find those chip 8833MPG, apple part 343-0042-B.

You will probably need another chip from another board. Did you check to make sure the battery is installed correctly and has voltage? I assume you did, but need to ask.
