There are loads of old ZX Spectrum games available to play online at ZX Spectrum.
So if you spent hours of your childhood playing Manic Miner, Jet Set Willy, Chuckie Egg and Horace goes Skiing you can now relive those moments for free. If you have never heard of them and are under 30 why not visit the site and see how games used to be played before we invented the Playstation, Gamebox and Wii.
