Technically abandonware is a bit of a dodgy concept - technically it is still illegal, it's just that it's so old no-one will know or care. MS do still own it, and you probably won't find it around in many places, there's not much call for it!
It is the look that I like. A primitive attempt at making a coulored OS. I collect these stuff like mad "The OS Collector". Getting a Mac OS 6 and under in coulor is like hitting gold. Win 1.1 is awesome too.
