Hi ,

I just received my pot amp pcb from happ, but there is no pinout or diagram. since I don't have the harness , I have no idea how to hook it up.
The SW trilogy wiring diagrams don't show that board at all !@^@#

Can anyone help me out ?

Thanks !

I would ask the one's that sold you the pcb. Sorry I can't be more help but not knowing where that is supposed to go, no schematics, and not knowing what you intended to do with this pcb, I am at a loss to help here.

That pcb is for the joystick (on upright version), and goes on the right side of the joystick assembly.
 
Found it !


HAPP CONTROLS POTENTIOMETER AMPLIFIER PCB #95-0013-00

The Happ Controls Pot Amp pcb is designed to be used with a Happ Controls analog
(potentiometer type) joystick to increase the effective range of the potentiometers on the
joystick.
For example, when operating at 5 volts, an unamplified joystick moved to it's extremes has
a voltage range at the potentiometer of only about .7 volts. With the Pot Amp pcb the
voltage range can be adjusted anywhere from .7 to 5 volts. The center voltage can also be
adjusted to voltages other than the usual 2.5 volts independently. This means that an
analog joystick equipped with a Pot Amp pcb can be used with any game hardware that
uses an analog type joystick operated at 5 or 12 volts. No special wiring is necessary;
power for the pcb is connected to the vertical and horizontal potentiometer +V and
Common connections.

Connection:
PCB pin Function
1. Vertical output
2. Horizontal output
3. Horizontal input
4. Vertical input
5. NC
6. Power supply common
7. +V (5 or 12 volts)

Adjustments:
VR1 Vertical center
VR2 Vertical range
VR3 Horizontal range
VR4 Horizontal center

To adjust, place joystick at it's center and adjust center trim pots to the desired
voltage (typically 2.5 volts). Then move the joystick to it's extremes and adjust
range trim pots to the desired voltage range (typically 3 volts or a bit less). The
adjustments are interactive, so it may be necessary to repeat the adjustments.

Great.....

I would have been able to help a bit more with the additional info but glad you found the info you needed and this will help others in the future.
 
yeah after reading my original post, I realized that I left out some important elements :D I was afraid I might not get peopl's attention if I went into all the gory details with what I'm trying to do.

I actually have a monkey ball panel who's missing the amp board. The joystick is pretty much the same as the Star Wars Trilogy stick, 2 large 5k pots. The Sega amp board is VERY different from the Happ board, as you can see.

6 pin header : joystick
4 pin header : naomi i/o


so now I think I can just do this:

Code:
naomi                 happ amp pcb                         joystick

v        ->           1
h        ->           2
                      3          ->                  h-pot center             
                      4          ->                  v-pot center
                      5
gnd      ->           6          ┬>                  h-pot gnd
                                 └>                  v-pot gnd
vcc      ->           7          ┬>                  h-pot vcc 
                                 └>                  v-pot vcc
 
Amp Bd used in Star Wars Trilogy

This amp bd was redundant and our engineers did not realize this when introducing it into system. Game Bd software already has range calibration so I always recommend cutting this junk pcb out of circuit. Simple thing if you have original wiring diagram in back of manual. Notice its not in drawing.
 
odd. this is not what I observed :/

I have a monkey ball & the banana controller who's missing the sega amp baord. When I tried to use it I only got a 76 - 92 range per pot in the calibration menu. Those values must not fall within a valid range because the player doesn't move when I start the game.

Once I added the amp board I was able to get a bigger range which the software seems to be like better.
 
Yeah I guess it depends on the stick, I'm trying to use a Planet Harrier stick (Sanwa JLK) on Star Wars Trilogy and I get a tiny range like +/- 15 from the centre pos. If I calibrate it, it works but the cursor jumps about 16 pixels at a time.

Anyway I got the pot amp board now, just need to wire it up...
