Did you know about this?

Someone, some how managed to upload Counter Strike on to my school's share drive. If you didn't know EXACTLY where to look, you would NEVER find I still think it is there...after nearly 20 years ..

Also those advanced calculators with hidden games in them.

Maybe @davepl1968 can tell us more.

Some model of HP oscilloscope has a game of Tetris on it just takes the right key combo and bam! Tetris is on screen use the button and knobs to play, certainly a strange easter egg for a lab grade oscope

I refuse to believe this to be true Next you’re going to tell me that gullible is written on the ceiling

Cool!
