Is Flight Unlimited the first true modern flight sim... and should I have run it on a 486 DX2?

Any question can be answered "yes" if you get to define your own parameters. Nevertheless, I would like to tell you about Flight Unlimited, why I think it does indeed deserve consideration for pioneering two vital tenets of the modern flight sim, and what it was like to play it on a 486 DX2/66, barely above the minimum spec. And what were we doing with a 486 that late in 1995 anyway?

Plus, while it may be an interesting diversion into the past to play Flight Unlimited on an emulation of suitably underpowered vintage hardware, there's also a case that when given more resources it's a better game than its immediate successor, the unique flight model and crisp software-rendered graphics eclipsing generic '90s GA sim techniques and blurry early 3D. At the very least, it was less of a pain to get running.

Yes, I did indeed spend a lot of time making those stupid rendered bits work. I'm still far too proud of that "virtual world" one even if it doesn't line up exactly right.

Bonus fact: that is indeed my original 286 in its original configuration as a 286 sitting on the floor of a very chaotic bedroom. I'm not sure why it's on the floor as it was definitely on some sort of desk most of the time, but the mess surrounding it and possibly my need to take a photo suggests some kind of transitional state for bedroom layout, computer, or both.
