This module is straight out of the Lunetta playbook. It is simply a CMOS 4018 with buffers on all of its inputs and outputs, along with a 4081 to enable further divisions.
The divide by is patch-programmable, simply patch whichever number you wish to divide by back into the input and feed it a clock. The other outputs will follow the 1/n at various phase differences depending upon what is going on.
You can get quite silly by feeding signals into the J1-J5 inputs (jam) and sending a high signal (anything over 1V) to the preset enable.
