The Furby was a hot toy in 1998. Kids wanted it, parents had visions of Gremins (don’t feed them after midnight!).
Actually, Furby is quite a sophisticated toy that was built with a Motorola 6502 microcontroller, the same chip used in the Apple II, the Commodore 64, and other computers. But how does one get all the motor control and voices out, given the limitations of the 6502? Get out the original source code written by David Hampton and Wayne Schulz.
Both Sean Riddle and the Internet Archive have copies of the original source code, which appears to have been released during a court filing.
If you’re into analyzing the code, you can join the ycombinator chat discussing the code.
