There's a lot of classic PC gaming available at these sites.

http://www.abandonia.com/

And there are some classics. Prepare to go "Oh! I remember that" and have your childhood dredged up.

Some of the bigger name titles though have kept their IP and still make you charge for it. Boo!!!

I dunno about abandonia.
The Discworld games were made playable on modern machines thanks to the rights holders giving parts of the engine code to the guys working on ScummVM, so the game hasn't properly been abandoned (and it woks better now than it did on my 486, astonishing).
