So it has clock and ground labeled on the PCB.
I understand the next step is to get a scope on it to see if it's 24 ppqn or per step clock output. Either way a simple divider will take care of that.

It is doable!

there will be a gate signal somewhere. the divider is already on board. the trick is finding it. that clock line on the board might be a lot higher than per gate. or it might be the gate. you do not need a scope but you could get a quality USB digital logic analyzer for $10 from china. failing that, could rig up a simple logic buffer and led driver to probe around with.

why don't you post the part numbers to the all IC and we can settle it that way. if you find a 4017 or 4022 it will be pin 14.
