24th Anniversary Macintosh

[Dave] sent in his retro Mac project. Putting new guts into an old mac isn’t really unheard of, but I liked his solution to use the original Mac 512k keyboard and mouse. He used an Atmel AT90USB162 to create his own standard USB HID device. The keyboard and mouse appear as a standard USB device, so the mac (or any modern USB PC) can identify use the keyboard and mouse without any additional software.
