Atari 2600 Atari 5200 Atari Lynx Bandai Wonderswan Colecovision Coleco Telstar Intellivision Magnovox Odyssey (did that come out here?) Nintendo Color TV Game Nokia NGage PC Engine/Turbo-Grafx Sega Pico
Judging from the same list mine is near enough the same, I have a hunch that I may have played the Wonderswan and NGage very briefly in a shop, but I really don't recall. I also never played the Philips CD-i (And I don't think I missed much!)
The Atari 2600 is definitely a console I'd like to add to my retro collection at some point, think it's an iconic piece of hardware and has versions of some real classic games on it.
Indeed, the Atari 2600 is the only mainstream console I've never played (I was born in the mid 80s).
