I haven't seen any, but I did post quite a while ago about modifying a 48T02
so I could mount a 3 volt lithium battery on top of the chip in a
home-brewed battery holder. It's not elegant, but it works.

In my crystal ball I'd like to be able to say that Dallas are going to fix
up the compatibility problems with the DS1642 and design a new version of
the part with an external 3 volt lithium cell holder, but... Wishful
thinking I'd say, but that would be the ideal solution, since then it's a
simple matter of replacing the cell while the machine is powered and then
it's safe for at least another 5 years.

I know of a supplier here in Sydney, Australia that sells the 48T02 and
48T08 NVRAM/RTC's, so I'm sure there must be suppliers elsewhere. Mark
Henderson (editor of the NVRAM/IDPROM FAQ) would probably know of a few
sources in the US and/or Canada.

Regards,

Craig.
