Slicing open the top of a 48T02 Sun Sparc chip to replace battery is that thing hollow or filled with epoxy?

In place of the Thomson chip I used this Dallas replacement on my Sparc.
Works well. If you want to replace the batt then you have your work cut
out for you. Cut carefully at the extremities and you will see leads for
the batt on either side. Can't do any harm by trying. The Tompson has a
'cap' on it for a batt. I did manage to 'replace' the batt on my Thompson
chip, but it was ugly. I cut the four posts securing the batt of the
Thompson to the 'business end' then soldered a battery carrier's leads to
the power inputs of the chip. Later my Dallas replacement arrived and I
mothballed my hacked version. I can take a picture of the hacked version
if you like. This is a fairly frequent question these days and my wife
and I received this weekend a Cannon Elph Powershot 100 as a late wedding
present so now I can offer this. The Dallas is poured epoxy....read
'don't even try. Call Dallas Semiconductor directly for a replacement.
Others will rape you. Good luck and happy hunting.
