[rescue] Sun Ultra 2 series PROMs

[rjtoegel]

May I make a suggestion?  The pins you mention may be the power for the chip
but the battery is internal.  IIRC some  have used a Dremel and ground into
the chip to connect an external battery across the dead internal battery with
no ill effects.  Sorry I'm fuzzy on the details but it should be in the
archives .
