The first part starts with just the Wavetek 145 synchronized in trig (one-shot) mode, which sounds sort of like a variable pulsewidth or filter as I change the frequency. I then switch to gate mode (0:22), which sounds like oscillator sync. Then I modulate the Wavetek 145's VCG input with the Wavetek 188 (0:50), then connect the 145's pulse output to the 188's trigger input (1:10). At this point it's some sort of sync-FM feedback loop. Finally, I activate the sweep on the 188 (1:20). Confused knob twiddling follows.

Well that was the plan from the start. I've recorded it already.
