Yahoo Games has some old arcade games... Invaders (pretty much the same thing as Space Invaders)... and Qbert!!!  Love this one!  They may have some more too... but I actually think it's more difficult to play these games without the Atari Joystick in my hand... haha.

Chuckie Egg, Manic Miner....

a very old text based RPG called "pirates" - anyone else remember getting stuck in an attic and trying to work out exactly what to do to get hold of the flotsam/jetsam?

another old text-based adventure (very early PC) of Hitchhikers Guide to the Galaxy.. wandering along conveyor belts finding 10 tons of whale meat...
