I think its 1995 or so. With SVGA AW, came new shapes and things like propellers. Also, real time instead of half-time
I have older versions of AW but they're platform specific - in my case Atari.
Here's the release notes dated 7-18-95. Believe it or not, the program runs in WinXP
New features of the 1.20 DOS release:
