I have a small box of dead NVRAM chips (48T02 from various sun4c machines). I
was thinking about recycling one for a clock project (PIC or 8051 or mc68k
based, depending on which way I jump). Are there any components other than
the battery in the potted lid? i.e., can I just remove it entirely or
do I have to perform delicate surgery to seperate the front leads and solder
wires onto the front of the I.C. where the lid used to connect?

I got "the hairy eyeball" for showing off stuff like this at work. I
soldered a 3V solder-tab lithium cell to a 9V battery snap and a 9V
battery cable to one of the aforementioned 48T02 NVRAMs. Got lots
of strange looks from the boss, but it was my spare from home when I
needed one right away and didn't want to wait for the replacements
from Mouser to show up.
