I cant claim to know exactly, but if memory serves me correctly, you Could
attmpt to setup the control panel in XP to see a generic input device (2
axes joystic) then see if the axes show up, most likely you will end up with
combined brake and throttle wich sucks.
But, there might been newer "XP" compatable "game port" drivers. I gave up
on TM many moos before XP was released. IMHO your best bet for a wheel
upgrrade that is USB connected. Cheaply, a lot of friends are getting good
use from the logitech DFP (digital force feedback pro?) it has like more
than (shoot I cannto recall more than 360 dgrees of movement of the wheel.
I personally bought me a logitech G25 (they are about $250 now) last week
and LOVE that dang thing, but I have understanding that the driver for Vista
is not out for it yet and the current driver is not fully functional
(profiles and settings not yet), so I have held off on installing vista
right now.
good luck. PS helps in most "Games" {as apposed to SIMS} to have the
joystic seen as ID 1 (sometimes depending on drivers entails disconnection
of all other joystick, some drivers though, will let you set each joystick
seperately).
good luck.
