Once you open it up, you'll probably remember the module. It should be
under a plastic cover, under the case's aluminum cover. The eprom is
soldered into the carrier that has the module (white ceramic piece).

It's a pain, but I've been able to unsolder the eprom and solder a
socket in place. You then need to modify the plastic cover...
