Hi AwesomeCobra,
I'm still running 2002 on a refurbished Dell XP machine hooked up to the TV downstairs.
If you want some real nostalgia pick up a copy of Flight Unlimited 3 and add some 3rd party aircraft. This sim features ai planes that rev up on the end of the runway and vertical air movements over high terrain. I have successfully soared a Cessna on the side of Mt Rainier with the engine off.
Real shame Looking Glass didn't keep developing their sim.
I'v also got a working Oric Atmos with original twin disc drive from the mid 1980's. The flight sim on that is appalling though.
