Thanks for the suggestions!

The RTC is an STMicroelectronics M48T86PC1 which is obsolete. They are available from various sources, but not Digikey and Mouser. I have ordered some. I just have never seem them before, so I wasn't looking for a large DIP package to contain a battery.  Live and learn.  I am interested to see if the batteries are good in the available "new" parts, since they are no longer made.
