Were those the steam powered chips?  :-DD

No. 3.6V powered chips, like all the cool modern stuff.

555 timer + 4017 logic ic.
Richard Head:
+1 for ZN414. It was like a crystal set on steroids. I built it into a "Tic-Tac"box. That was early 70's.
Tandy:
This thread raises an interesting related question of how you got started and for many it will be the opposite way round today compared to 20 or 30 years ago. I started out with simple circuits and took a while to before I first got to experiment with an IC. For me; like many it was a 555 timer, at school in fact.

Now people are likely to do it the other way round, start out with a microcontroller board to do something interesting and then later progress to learning about fundamental electronic principles as their interest develops.

As much as TTL, Dave, or even more? Never used them.

I started with CMOS and almost immediately bought a masive list of TTLs.
