Doh!!! I wish I had a dime for everytime I've made that blunder.
I was pretty loopy and bleary eyed by the time I got around to adding
the 12/24hr switch. It was the last thing I added. I've still got to
do some fiddling to get the timing more accurate. I might need to get rid
of the INTIM counters in the VBLANK and OVERSCAN and do a cycle by cycle
count instead (GASP!) As well as very closely count my scanlines.
Right now the darn thing is gaining a half second ever minute wich adds up
pretty fast.

But I should have all the kinks worked out by the end of the week.

I was really quite suprised at the demand I got for that first clock
demo of mine on a cart. I only made it to see how easy it would be to 
build a clock for the V-pet and was suprised that more people were
interested in the clock than the V-pet. But I decided if I was going to
release the clock on a cart I should take some time and jazz it up a bit.
Thank Bira for the long weekend. I finally got some time to do some
coding.

Now if I can just work this video clock into a set background on Drew Carey
or Friends I should be able to retire on the sales it will generate. ;)

Woohoo!!! Then I'll have to remember if I touch the scanlines while fine
tuning the timing to add or take away from them in twos.

I guess whatever is at that zero page location I was reading just happens
to be an 8.
