"Here is a very rare, early, kit-built Serge. One panel has a dual Negative Slew module, two Programmer modules, and a triple Bi-Directional Router. The second panel includes a module labeled "Dual 7486" (a ring-mod or dual VCA or both?), Sequencer, Dual Processor, Envelope Generator, dual
Positive Slew, and dual Negative Slew. The amazing thing about the slew modules is that they can be cycled for use as oscillators (audio or LFO) or triggered as envelopes--they are precursors to the infamous Serge DSG. The Envelope Generator can be used as a pulse-width-modulated oscillator. The Sequencer is a gate sequencer that can be used to clock the programmer to make a CV sequencer. These two panels can serve many purposes: 
7 oscillators or LFOs or a bunch of simple envelope generators, or anything in between. They can easily be used as an instrument on their own or interfaced with other modular gear.Everything works on these panels except the the top half of the Dual Processor, which won't pass signal. The pitches I was getting by cycling the Slews were sometimes unstable and quirky, but sounded good otherwise. The power supply gets pretty warm.
I'm sure you've noticed that someone built these panels with 1/8" (3.5mm) jacks. Notice the switch between the two programmers; it switches between the two top rows of the Programmers, sending to the jack on its left. The ground wire on one of the panels doesn't have a solder lug, but it is still easy to attach that wire to the PSU. The pots may benefit from a cleaning, but all work.Since this is a vintage kit-built synthesizer it is sold strictly as-is..."
