DALLAS DS1287 chip examined

Following the directions on the excellent: http://www.mcamafia.de/mcapage0/dsrework.htm page, I  exposed the internal pins on DALLAS DS1287 RTC chip on the spare IO board to see if the battery had died. It measured a healthy? 2.89V (should be 3.00V). So I suspect that's not the problem on this board. I used a craft knife, cutting away carefully at the pin positions until I exposed enough to cut them.
