We all hate them.
Those stupid dallas chips that were put in everything from SGI's to IBM computers.
My Model 30 greeted me the other day to a 161 and 163 error that could not be corrected and indicating that the dallas chip had gone south. Then today I managed to get hold of a handful of regular (but dead) dallas chips.
I then thought about the battery hack for sun computers and got an idea. Please refer to the photos below for even more detail.
I grabbed one unlucky subject and with my dremel set out to see what was under the hood. It took a while but I first found the crystal followed by the battery in the middle and then finally the battery terminals themselves.
Going with my volt meter I determined that the battery was indeed dead.
now knowing where the battery terminals were, I grabbed another chip (of a different model) and with the dremel dug out a cavity to the two battery terminals. A quick check with the meter indeed proved it was the battery terminals.
My theory is that if I were to figure out how to cut the battery leads (not soldered on like in a sun) and install a regular CMOS battery the chip would be as good as new.
Do you think it's possible? I can see at least four computers I own that would need this.
On another note. The powder made during the drilling closely resembles moon dust.
