Playing Tetris on an Oscilloscope

Tetris on an oscilloscope

Have engineers stopped putting Easter eggs into technology lately? It’s always been a fun way to connect with your more advanced customer base (i.e. hackers) — anyway, here’s a great Easter egg you can find on the Hewlett Packard 54600B Oscilloscop — Tetris!

[RaffttaM] discovered this trick when a coworker let him know that one of the oscilloscopes in the lab had the hidden feature. A little fiddling later and a game of Tetris was revealed. If you press the Print/Utility button on the 54600B oscilloscope, followed by pressing the second and third button below the screen at the same time, you can launch the game!

Another cool embedded Easter egg is in the Game Boy Printer — If you hold the feed button during power up it spits out a Mario themed image! One of our readers even managed to hack the printer to show the Hack a Day Logo instead!

Do you know of any more modern tech with cool (and sneaky!) Easter eggs? Let us know by sending in a tip!
