hi guys,

I'm near to finish the Magic Smke Board Rev. 2 for the TH-102 ..

in the doc there is some switching I do not understand , is it possible that there is an error??
all things to CN103???

CN13 and CN14 are not mentioned anywhere else in the cabling doc .. so I think it must be like marked in red on image below ..

I posted this in the other thread as well; you are correct. Here's a rundown of all the connectors:

Quote:

If you're looking for a little more info on the board image I posted, here are the connector functions:

Left Edge:
CN7 Linear CV In jack
CN8 Linear CV attenuator
CN1 Coarse Tune
CN2 Fine Tune
CN101 FM 2 In jack
CN102 FM 2 attenuator

Top Edge:
CN105 Square Suboctave out
CN110 Pulse Suboctave out
CN108 PWM In attenuator
CN107 PWM In jack
CN106 PWM Initial
CN109 Pulse Out
CN104 Rampoid Out
CN15 Tri - Ramp / Sine Out
CN16 Square Out

Bottom Edge:
CN4 1V/Octave CV in (switching jack)
CN3 Keyboard CV in (from internal bus)
CN6 FM 1 In attenuator
CN5 FM 1 In jack
CN9 Skew Initial
CN10 Skew CN In jack
CN11 Skew attenuator
CN103 Hi / Low cap switch
CN12 Sync In

Middle:
CN13 S1a (Tri - Ramp / Sine Select switch)
CN14 S1b (Tri - Ramp / Sine Select switch)

Right Edge:
CN17 DC Power In (4 pin .156" Blacet style)
CN18 & CN19 DC Power In (6 pin .100")

Whew! Lotsa connectors. But we do have
* Tri -Ramp / Sine Out
* Pulse Out (derived from Tri - Ramp)
* Suboctave (derived from Pulse)
* Square Out
* Suboctave (derived from Square)
* Rampoid Out

* Two Expo FM Inputs with attenuators
* Linear CV Input with attenuator
* 1V/Octave CV Input

* Tri - Ramp Skew CV Input with attenuator
* PWM Input with attenuator

* Sync Input
