[Coco] DS1216C SmartWatch source?

[Christopher Barnett Fox]

I recall someone on the list some time ago was looking at adding a SmartWatch (Dallas Semiconductor?) to their CoCo. Has anyone found a good source for these? I'm specifically looking for the DS1216C variant, to upgrade a cool little 8085 trainer I recently acquired (the EMAC "Primer"). Would the same SmartWatch variant also work as an RTC upgrade for the CoCo?

Thanks!
