[Coco] Clock chips-- DS1307 today

[George Ramsower]

 I searched for "Smartwatch" and found a lot of stuff but nothing we could 
use on a coco until I did another search for DS1307 and found some 
interesting things on eBay for just a couple of dollars, from China.
 Most are designed for the Arduino so....

 I'm wondering if they could be used on our Cocos. I'm sure they willl need 
some address decoding and there are some old boards some of us still use 
with unused chip select line that could access these little boards. 
Otherwise, it would require another board to decode the address and access 
them, I figure. I know nothing about how to use them other than they should 
be similar in data transfer as was the old smartwatch. Maybe the old 
smartwatch drive could be modified to access the new address?

 Ideas?

 Here's how I found them...
 I went to eBay and searched for DS1307. That's it.
