Not sure what you meant by the "9x" in this context -- Windows 95 and 98? That, granted, has zero chance of being open sourced.
Yes, I know. Still nothing around as good as MS-DOS 7.10a (WIN 4.10.2222)
FreeDOS still sucks, kinda. Udo Kuntz's Enhanced DOS (based on open source Caldera/DRDOS), Paragon DOS, or ROMDOS are great stand alone, but there really is no GUI other than Win3x or Win9x, and those really require MS-DOS for really good FAT32 and LFN support.

Yeah, I meant Win95-WinME. and one could include Win3x, though probably 3.11wfwg would be the only one to worry about. Yes, I know they won't open their source, and yes, I know they won't release specs so an open community can write their own, but that's a damn shame, and a mistake too, IMHO.
