 What are/were the most popular battery-backed
 real time clock accessories for the Color Computer family?
 
 
Mark,

 It is also possible to create your own RTC which is what I did.

 I installed a DS1216 SmartWatch (was sold by Radio Shack) in an TRS-80 RS-232 pack after removing the ROM which I never used. It is a little tricky as the SmartWatch comes in a larger 28-pin base than the RS-232 ROM socket; 24-pin.
 I also wrote my own software so the RTC could be used from both Basic and OS-9.

 As an aside, the battery in the SmartWatch died and I was able to break some chip pins and add an external battery.
