I ran a PC Shop in 1995-1997 I was run out of business by Big Box stores offering low cost PCs using the AOL $500 Internet Rebate that locked people into a 3 or 5 year AOL $35/month contract. I tried to convince people that they could get on the same Internet with Brick.net and if they paid for a year in advance they would only pay $9.99 a month total and save money over using AOL. I sold a $700 PC Clone with GNU/Linux or Windows 95, and the Big Box stores sold the Packard Bell system with the same specs for $200 after the $500 Internet rebate.
I hear there are people still paying AOL for dial-up access on older Macs and PCs. So I am not surprised to see the old AOL clients still work mostly.
The Basilisk II emulator needs some system files to get CD and TCP/IP networking to work in Windows. http://basilisk.cebix.net/

Some people use Sheepshaver instead http://www.emaculation.com/doku.php/sheepshaver_online_guide
You also need an old version of SDL and GTK+ to make it work with Windows.
These Mac emulators could be upgraded to the latest technology for the latest SDL and GTK+ libraries, the source code is available.
The hard part is getting the Macintosh ROM, Apple made System 7.X available for free, but getting the ROM is hard. You'd need access to a 68K Mac and a floppy drive to copy the ROM to and copy it over to a modern computer using a USB floppy drive and only the 1.44M format is supported not the 880K format. Some ROMs are on the Internet and I won't link to them for piracy issues, but they should be found via web searches.
