OK y'all...I spend way too much time surfing the internet at work...but I've have found THE SPOT!
So, for all you 80's children out there who loved Ms.Pacman, DonkeyKong, Centipede and Atari games like Space Invaders and Frogger.....this is just for you....!!!
These games are Java emulators. So, make sure your browser is set to use Java. (most are already java enabled, by default) The games will take a few seconds to load and the instructions (which keys to use) are at the bottom of the page.
