Glenn Jones of A2 Retro Systems has developed an Ethernet card for the Apple ][, ][+, //e, GS, III, etc. It works with Contiki, which includes drivers for the card and a TCP/IP stack. You can watch an embedded YouTube video of Contiki and the Ethernet card in action here. He's also working on a way to get a USB port onto an Apple II.

Fire up those old Apple IIs, and get some old-school web-browsing done! For starters, you might want to check out Apple2.org or Apple2History.org. Personally, I prefer the latter, as the former -- while full of useful information -- is a real pain to navigate.
