[Coco] MM/1 RTC RIP

[Bruce W. Calkins]

I fixed one on a PC where I broke open the clock "chip" and broke the 
battery lead and added a external battery holder and battery.  And before I 
got a Dremel I used Dremel bits in a 1/4" drill.  It sounds like this guy 
did much the same as I did.

Good luck,

Bruce W.
