I would imagine many folks who are running NextStep on actual NIHS hardware (not in an emulator) remember the days of the gopher information system (that originated at the Univ of Minn, home of the Golden Gophers). It slightly pre-dated the 1994-'95 explosion of the WWW/HTML (the kraken that then ate the Internet) so, say, 1992-95 as its heyday. For those who do not, gopher client programs would read formatted text from gopher servers (much as web browsers read HTML pages from web servers), which would include links to both documents on the server as well as documents on other gopher servers (sound familiar?).
Anyway, gopher servers require very little processing power, and the same goes for the clients. As it turns out, in addition to HTML, the Omnigroup folks built OmniWeb 2.7 to also understand the gopher protocol. A good place to start is Cameron Kaiser's gopherhole, gopher://gopher.floodgap.com He also runs the only remaining Veronica gopher search engine. Another font of gopher knowledge is
http://www.jumpjet.info/Offbeat-Internet/Gopher/Repository/depot.htm (yes, yes, it's on the web but note that it is not https & is fully readable by OmniWeb), with an archive of client software
http://www.jumpjet.info/Offbeat-Internet/Gopher/Clients/clients.htm if you'd like to try those out (note that there's an excellent client in the Nextcomputers.org archive: gopher1.3.3b
(Cameron also has a comprehensive collection on floodgap.com)
Another great site is a gateway to Wikipedia! Try gopher://gopherpedia.com
So - no excuse not to fire up ye olde NeXTcube/station and run around in gopher holes with OmniWeb. Report back here with the interesting treasures you've dug up...
