Windows 95, 98, ME setup - (Highly recommended, one of the key advantages of Windows 95/98 over Win 3.1 is the built in Internet support)
Our setup doesn't yet operate on windows XP so use these XP setup instructions
Windows 3.1- (Win3.1 doesn't include TCP/IP so it is definitely easier to bite the bullet and upgrade to Windows 95/98 etc.. Networking, such as Internet access, is one of the key advantages to newer windows.)
We no longer supply software for Windows 3.1 but the expert hobbyist can probably find what they need at http://classic.tucows.com/preview/4770.html Our support techs are no longer trained to help on this.
Windows NT - Dialup networking setup.
Mac OS 7.6.1, 8 or 9 - basic setup.
