Desperate help needed regarding Happ Optical Rotaries and Optipac

[antony30bc]

Originally I tried using trackball interface of a KE72T to hook up my two optical sticks. After giving up on this idea I ordered an Optipac, cut the end off my KE72 cable, and wired the optipac  up. I couldn;'t get both sticks to register any rotary movement originally, only 1 at a time, until I swapped the jumper on the Optipac to Hi. After doing this within Mame games, Ikari warriors etc, both axis showed rotation. Now my concern is that the rotation is both jerky and spastic, and only unidirectional. If I rotate the stick to the left, the rotation still occurs to the right. Whereas if I use a mouse for this function the rotation will occur based on if I am moving postive x or negative x. Also I spliced the two ground and +5 v wires together for hooking to the single +5v and GND connector on the Optipac.

Anyone have suggestions, I am growing desperate at this point.

Oh yes I forgot to mention, rotating the sticks seems to have 0 impact on mouse curser in windows.

Actually I ran the RawMouse program from Jake's Analog XP site that shows mouse info and it appears that rotation in either axis will move the mouse 1 coordinate, then back. Kind of a stutter effect.

I have heard you need to wire them all to the trackball input - make player 1 rotary as X-axis and player 2 as y-axis.  Analogmame can then be used which will split the inputs for the 2 players.  I think the reason that having them wired to 2 different inputs don't work is because xp doesn't allow 2 rotary controls or something like that.

Fixed the problem thanks to this thread.

I highly recommend anyone with the optical rotaries check the screws and brackets holding the PCB to the joystick. Both of mine were also shorted by contact with the bracket, similar to as mentioned in the referenced thread.
