Just thought I'd add some info about my wheel panel, since I didn't really say much about it:
Pole Position wheel hardware, with Super Sprint wheel, interfaced with Oscar mouse hack,
Hard Drivin' (compact) 4-way shifter (via IPAC in the cabinet itself),
Um, 3 buttons (again via IPAC),
Happ dual pedals, interfaced with an AKI.
You can't see them in the shots on this page but see page one of this thread for pics of the pedals.
