I'd have had to wait for my ST replacement NVRAM without the assist from Tom Miller.
Wherever did you find a DS1213? Digikey and Mouser don't have them. I doubt that any of the ones on eBay have good batteries. But you can see the outline of the tiny lithium cells potted on the underside, so a bit of Dremel work would allow fitting a larger pair of cells in holders in the unused DIP footprints in the left front corner of the board.
The next issue is what data is stored in these? It's obviously not the RTC or anything else I can determine such as operating hours, serial number, etc.
The only downside is now I need an SD-24 and an SD-32 ;-)
