A new listing for a rare Twentieth Anniversary Macintosh has appeared on eBay. Recognized as the first major design project for Jonathan Ive, the TAM was introduced as a limited production in the spring of 1997. Only 12,000 machines were ever produced, and 399 of those were kept by apple to be used as spare parts. The system comes in all of its original packaging and includes all of the accessories that came with the system when it was shipped. Biding will remain open until June 23 with shipping limited to locations with the United States.
