I have a quadruplet of U5s that has one working NVRAM between them. I
pulled one open to see if I could employ the battery modification that has
been used by others (several on this list, no less)... but the U5
appears to have quite a different NVRAM module.
The earlier ones that I've seen modification pictures of have the
'backpack' battery/xtal, and just a potted nub that requires scraping open
to provide access to the battery contacts.
The U5 NVRAMs are fully encased in a plastic housing that appears to be
epoxy bonded onto the IC/battery/xtal.
Are these also modifyable, or should I suck it up and pay $15 a NVRAM at
Mouser?
Thanks;
