Classic II motherboard- Where is PRAM data stored?

[Rjp663]

I’ve recapped my early version motherboard and replaced the PRAM battery. However I’m still seeing the loss of time, date and mouse settings when the classic is turned off.

I have checked the battery voltage back to chip U12 pin 7, then to pin 12 on the EGRET chip. That path is good. 
 

Question- what chip stores the PRAM data?

thank you.

And the answer is....U10 EGRET chip.  Another custom Apple chip.
