Almost 20 years on, the Logitech Wingman Formula Force still works in windows. Released around the time USB was just arriving on the market, these robust wheels date from back in 1998.
Logitech discontinued driver development in 2006, however Saitek did release a 64bit driver based on the Immersion SDK. A primitive Force feedback design by today's standards, but it still works with most modern games.
This driver was adapted by Sly_North from the below Saitek source.
To breath a new bit of life into the Logitech Wingman Formula Force, here is a Windows 10 Driver (signed) that will permit installation into Win10 x64 bit without the need to disable driver signing.
UPDATE [Jan 2020] - This driver no longer installs on fresh Windows 10 OS. This is due to MS changing signing requirements under fresh installs in Windows 10. The below driver is signed with SHA-1, which is no longer trusted, thus not supported in newer releases of Windows 10. I'm looking for a volunteer to re-sign these driver with SHA256 as per Practical Windows Code and Driver Signing
