Reverse engineering the 76477 "Space Invaders" sound effect chip from die photos
Now _this_ is reversing:
Remember the old video game Space Invaders? Some of its sound effects were provided by a chip called the 76477 Complex Sound Generation chip. While the sound effects1 produced by this 1978 chip seem primitive today, it was used in many video games, pinball games. But what's inside this chip and how does it work internally? By reverse-engineering the chip from die photos, we can find out. (Photos courtesy of Sean Riddle.) In this article, I explain how the analog circuits of this chip works and show how the hundreds of transistors on the silicon die form the circuits of this complex chip.

This really exists. “Do I take risks in order to gobble up the fruit symbol in the middle of the screen? I do not, and neither should you. Like the fat and harmless saucer in Missile Command (q.v.), the fruit symbol is there simply to tempt you into hubristic sorties. Bag it.”
