[Coco] Survey of Coco realtime clock users

[Robert Gault]

I'd like to get an idea of how many people have some type of realtime 
clock installed in a Coco system. Don't bother replying regards emulators.

Indicate what chip you have and where it is installed. My reason for 
asking, besides curiosity, is to find out how many users are subject to 
battery wear out and clock failure.

For example, I have a Smartwatch DS1216 (sold at one time by Tandy) 
installed in my RS-232 pak instead of the ROM. Just had to replace the 
battery.
