Inspired form the all transistor digital clock: https://forum.allaboutcircuits.com/threads/counter-circuits-for-all-transistor-digital-clock.156950/
I did not want to hi-jack the thread so i created this for further discussion.
I bread boarded my version to test it out, including the pulse generator. I didnt have exact component value:
C1 = 100nF
C2 = 10nF
PNPs 2n4403
NPNs 2n4401
