Here's a great video from technabob that shows an Apple IIe displaying archived Tweets from a 5.25-inch floppy disk, complete with lo-res graphics.
Here's how it works. Modder Yergacheffe uses a PC for interacting with Twitter. He hacked together a PC-to-Apple IIe interface for moving data to the Apple from the PC's USB port. Next, he wrote some custom 6502-assembler code that displays Tweets on the Apple IIe and also converts users' Twitter avatars into those gorgeous, chunky lo-res graphics.
Finally, tweets are saved to the floppy for later playback. Too busy to attend to Twitter? Capture the action and play it back later, retro-style. We love it.
