Battery location?

Postby Compuphonic » Thu Oct 02, 2008 7:46 am

Hi everyone,

I thought I'd better check the battery in my JP-4, but can't seem to find it! Do I need to remove the mother-board? It is one of the last JP-4s made (September 1981).

Also, what does one replace it with?

Any pointers would be much appreciated!
