Has anybody used one of these to wire up a Pole Position Steering Wheel using the existing optic board on the steering wheel? --- End quote --- The existing optic board is NOT directly compatible. Someone has a hack posted here somewhere for removing most of the circuitry and making it a dumb encoder compatible with a mouse hack... --Chris |

Talk to oscarcontrols about interfacing a steering wheel. They even have a $9 mouse prehacked. |

I emailed OscarControls last night and this is what they said. "The original Atari optic boards will work with the USB interface. The Atari board has the same pinout as the Happ board as shown here: http://www.ultimarc.com/optipac4.html." I guess I will give it and see. |

There are lots of ways to do the steering wheel and pedals, but what I want to know is: How can you interface the shifter?! It has a miscroswitch that is either on or off (hi or low in the game) but the mame code works off of a button press to switch between high and low. Anyone have any ideas? |

Anyone have any ideas? --- End quote --- Actually there are 3 ways MAME handles shifters (AFAIK): 1) Same input toggles hi/lo (eg Pole Position) 2) One input for hi, one input for lo (eg OutRun) 3) Input on = lo, release = hi (eg ChaseHQ) 3) is exactly how (most) shifters work, so will work perfectly with a real shifter. 2) would work if you wired a separate input to the NC contact on the shifter microswitch, but it will always be sending keypresses (with a keyboard encoder anyway). I'm not sure the best way to deal with 1), without some coding work in MAME. I would be interested to know if the shifter inputs in MAME are accurately emulated. From the little research I have done I think some at least are not. I get the impression this is another case of the driver author doing 'what they think'. |
