It seems the differences between the 3 OSs (2.0,2.1,3.0) are very minor indeed. The difference between 2.1 and 3.0, (as far as I know) is some support for a4000 AGA modes, while the main differences between 2.0 and 2.1 are the extra prefs, and PCMIA support. The prefs (and locale.library) aren't really a support issue versus 2.0 which simply doesn't have them ( oops cross-dos too!), andd 3.0 is the same and only in hardware which can see the difference. are there more major differences that I've missed? I think 3.0 should be 4.0.. we don't want the world to think our gui is less maturre than Windows3.1 do we? ;-}
