The Internet Adapter (TIA)

 We used the free, open-source, Slirp on our Linux box (which, bonus, also supported PPP). But the “official” campus dial-up Internet access system was a paid ($495 for a site license? Sounds about right) copy of The Internet Adapter. Hard to find any information about that obsolete piece of tech 25 years later, but, Wired to the rescue... (Why, yes, I am cleaning out my open tabs, why do you ask?)
