A couple of years ago just for fun I started from scratch and designed a nixie clock circuit from the ground up (pun intended), that uses (6) 74HC160 counters.
The ic count is 17 packages for a plain 24-hour only clock. The package count goes to 18 for a 12/24 hour selectable version. It sets using thumbwheel switches and a push button. I know that to all of you guys out there who use processors that this seems elementary. However, even so, I am still rather pleased with the '160 clock.
