Thanks for looking into this, guys.

That's where I ended up as well, without breadboarding it.
The enabler disables the counting, if I understand the sheet correctly.

Exactly This will be both a quick method, and easy enough to make.
Lot's of wires that I will not cross (I'm taking that advice)

Yep. Got it.

Also, I think that the 4017+4081 is the best sollution, better then the
'oldschool'
sequencing methods: I expect this stuff to work faster / correcter at high
rates.

Thanks a bundle,
