> I doubt there is any specialised hardware on the Windows 95 machines, the specialised hardware is likely connected to something else.

Based on my experience with older government systems, this is likely an incorrect assumption. It was extremely popular in the 90s to create custom hardware that integrated directly to windows machines. I've had to reverse engineer so many drivers to upgrade old bespoke equipment to integrate with newer OSs

The reason why I doubt it for the FAA, is I know in the 1990s the core ATC system ran on IBM mainframes and the specialised equipment was directly or indirectly connected to the mainframes. Hence, I expect the Windows PCs were used to run terminal emulators, email/messaging, various auxiliary applications.
