...I'm looking to make a little addon for my PC and I need a little

after making 3 time/date displays using 7-segment (numbers) and
10-segment (letters) LED displays. One of them should actually show
the
correct time, the others I'd like to show other static times,
preferably
with the option to change them occasionally. The latter parts should
be
within my reach but the actual clock is a bit more of a problem, our
school was a bit crap and didn't actually teach us how to do that.

I would ask in the electronics groups.
sci.electronics...

Good luck.





The other thing is that it needs to be powered from the PC's power
supply, so it'll need to run on either 5V or 12V, with some form of
battery backup to power just the real clock when the machine is
switched
off. If somehow it could be made to display the system's internal
time
that would be wonderful, but not necessary.

Any help at all would be vastly appreciated.
