I know that a PIC could be programemd to do this.

Yes a PIC.

You're not allowed to say "use a pic" without providing a schematic
and full code listing.

OK, use an '8051' then. 63 cents indicative price for this one. I don't
do PIC code but I could ask my nephew to do that !.

My first thought was a 3-bit shift register.

Far too many parts !

Note that the OP was aware that a PIC could be used, but asked for
"the simplest collection of logic chips" which would do the job.

Oh, OK. A counter with auto-reset is the answer then.

A PIC isn't a logic chip?
It might not be a "discrete" logic chip, but I'm pretty sure there is
some kinda' logic in there. :)

---
Of course, but the OP's query rejected it as a viable candidate.

The OP stated :
"I know that a PIC could be programemd to do this."
Is that a rejection?

---
Well, of course!

By mentioning it and asking for another way to do it he was tacitly
rejecting it.

Naturally, the info provided doesn't really give us the full domain of
the problem, and I'm just yanking your chain.......

Have fun, I yank back! ;)
