Just a footnote. MacTCP was only available as part of an Apple site-license. However it was also commonly distributed illegally by ISPs and magazines. Most home Mac users on the internet prior to about 1996 probably inadvertently warezed it. (MacSLIP/MacPPP was freeware however.)
Not that I'm suggesting you donate to Apple anymore than you already do :)
Not exactly true. The book Internet Starter Kit for Macintosh by Adam Engst (of TidBITS fame) also provided a licensed version. The ISP I worked for way back then distributed the book to new Mac users in order for them to be legal.
