Some mistakes/distortions are readily apparent.
What a surprise, eh?
E.g. Appendix A (page 162 of the file).
It says "Win 3.x" had NetBIOS support in "November 1993". Windows 3.1 came out in March 1992 (a month before OS/2 2.0). It didn't have NetBIOS support built-in. Windows for Workgroups 3.1 was the version of Win3 that had NetBIOS support, IIRC. It came out [link|http://support.microsoft.com/default.aspx?scid=kb;EN-US;q126746|in October 1992]. 3.11 added additional features and came out in November 1993.
But "Windows 3.x" never had IPX/SPX, NetBIOS, SMB/CIFS networking features in the standard Windows package from Microsoft, unless I'm mistaken. Otherwise, Trumpet Winsock, Crynwar packet drivers and the like wouldn't have had a market.
I'm sure there are similar distortions in the rest of the paper.
Cheers,
Scott.
