Google Picture search is your friend
you must mean Google Images. i saw that picture before i started the thread, that's how i determined the battery was on the board with the headphone jack. it'll be interesting to see how the boards are arranged, i'd crack it open but won't do so until i have the battery. i may replace the battery in my other older rack synths- the UltraProteus, Pro/cussion, Matrix-1000 as long as i'm going through the trouble.
