I use processors and this doesn't seem elementary to me!
I wouldn't say that a microcontroller is more difficult to use than
straight logic. On the contrary, I always refer to my penchant for using
microcontrollers as "cheating".. or the software engineer's way out:
"Only design enough electronics so that you can write the rest in
software". ;)
Some day I'll be good enough to design my own clock using straight logic
chips..

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.
