Yes, it has a Mostek 48T02. I would make a dump of the NVRAM ASAP. I
didn't get the chance to do this to mine, because mine failed to start at
all, displaying simply "NVBATLOW" on the serial console, and nothing else
afterward.

I will post a procedure for saving NVRAM contents to this list this
evening. With luck there will be a few things still left in there, which
could mean the difference between heartache and happiness when you replace
the NVRAM.

I can also give enough information on replacing the NVRAM to get things
mostly running again, though as I mentioned I am still finding problems
with missing or uninitialized data in my NVRAM.

ok
