The 8-bit Acorn Atom

Acorn Atom (released 1980) was the forerunner to the popular BBC micro and a decent little 8-bit home computing classic on its own. Also, it's gradually becoming quite the rarity and usually sells for slightly more than 50£. Find out more about the Atom at Wikipedia, grab an emulator here, oh, and go for the micro itself by bidding on this ebay Acorn Atom auction. Seller ships to UK only.
