[rescue] Problems trying to resurrect a SparcStation IPC

[Michael A. Turner]

	Someone once posted a doc on how to do this, involved a file and a
watch battery. File the chip down until you can see two contacts and =
solder
the battery to those contacts. Sounded like fun to me as I need to do =
this
now also for a new IPC I got. If anyone has those instructions laying =
around
can you repost them?=20


<snip>

I think I remember that it's possible to solder a new battery on top of
the NVRAM chip if you do it *very*carefully*.

I'm sure someone knows more about this than I do... Right? Seems to
always be true here... ;)
