Classic video games from the 1970s and 1980s have been put online by the Internet Archive and can be played within a web browser for nothing.
The collection has launched with games from five early home consoles, including the Atari 2600 and Colecovision.
The games do not have sound, but will soon, the Internet Archive said.
"In coming months, the playable software collection will expand greatly," archivist Jason Scott wrote.
"Making these vintage games available to the world, instantly, allows for commentary, education, enjoyment and memory for the history they are a part of."
The other machines included are the Atari 7800, the Magnavox Odyssey (known as the Philips Videopac G7000 in Europe) and the Astrocade.
Well-recognised titles such as Pacman, Space Invaders and Frogger are all in the archive - with more consoles and games expected soon.

Yeah, "legal gray area", no kidding! I wonder how long some of those will be up before they're removed.

Interesting idea though, be cool to follow up on it.
