I've uploaded the Win9x driver & demo disc for the Saitek R4 Force/Racing Wheel here: https://archive.org/details/saitek-r4
It's loaded with game demos which is obviously not suitable for the Vogons library. So I provided two zip files on that page:
- Full disc content including demo games: R4_Full_Disc.zip (327MB)
- Drivers & manuals only: R4_Drivers_Only.zip (26MB)
With either download, just run Saitek95.exe for the installer. Once the drivers are installed, you then need to go into joystick control panel, manually add a device, and select the Saitek wheel from the list.
