In August 2001 I logged onto AOL with a Mac Plus running AOL 2.7. I was able to send and receive e-mail, check weather and stocks, and even created a new screen name in the process. I used a 28.8 modem (Zoom brand) and found the experience to be quite good (even in terms of speed). The following month I got a Color Classic and put the Plus in storage for a while. When I tried to sign on again the following summer it wouldn't work from the Plus, saying I needed at least AOL 3.0 (which doesn't work on even the most souped-up Plus).

That being said I would imagine dialup support for OS 9 and pre-G3 machines will be gone by the end of 2010 across the board. I'm surprised AOL even was able to connect me in 2001.
