The Twentieth Anniversary Macintosh, also known as TAM, was released in March of 1997. Due to its unique design, TAM didn't fit into any Apple product line. It was the original version of nowadays’s iMac, with everything held in a thin box in the back of the screen.
Not only the design but also the significantly high price of the computer set it apart from the rest of the technology of the time. Back then the TAM's cost was $7,500, which would be around $11,200 today.
However, in just a couple of months, the price went down to $1,995. The production was stopped when it was completely sold out.
