Seems there has been a lot of interest in clocks of one form or another
recently. I finally found a computer that had an old version of my 1000 day
countdown timer using a 16c84.  I have zipped the files and added them to my
web page.

To get a copy, point your browser to:

(The www5 is not a typo. I have no idea why my ISP did this...)

From the table of contents, go to computing, and then to microcontrollers.

Have fun, hope it can be useful.

P.S. I don't have a copy of the count up source at the house, only at work.
I won't make it back to the office until January 5th.  Sometime after that I
should have the count up source here as well.
