This sounds very helpful. I wish i could just recode the PIC based
digital clock since all the PIC code is offered from this site:
http://hobby_elec.piclist.com/e_pic6_76.htm
Why can't you?
The circuit already uses a BCD decoder for driving six 7-segment LED
displays. There a link to the circuit I refer which I purchased most
of the parts. It uses a PIC and also a CPLD for 3 to 8 decoder, some
divider for time accuracy and debounce logic. I use a 10Mhz metal-can
oscillator for the time keeping input. I cannot find the oscillator
used in the original description. Perhaps the circuit shown to the
group can loosen a few extra suggestions. Thanks for your
suggestions.
This circuit can be found on this link:

How many suggestions do you need?
Do you want to maintain the 7-segment, and _add_ the seconds roulette
wheel?
Then you'll either need 8x 8-bit shift registers, 4X 4-to-16 decoders,
or a matrix.
Or another PIC, which means you'll have to learn to program a PIC anyway.
Do you want a strictly hardware solution to this, without any programming
involved _at all_? Then be prepared to spend about a couple of hundred
bucks on discrete logic and perfboards.
Good Luck!
