How much would you pay for the first Apple machine ever made? One Apple fan on Tuesday shelled out $213,600 for an Apple-1 when it went up for auction at Christie's in London.

The unknown buyer bought the device for £133,250. When the auction was , Christie's estimated that the Apple-1 could bring in between $160,300 and $240,450. The Apple-1 originally cost $666.66; in total, the buyer paid $741.66 for it more than 30 years ago.

"Introduced in July 1976, the Apple-1 was sold without a casing, power supply, keyboard or monitor," according to the auction listing. "However, because the motherboard was completely pre-assembled, it represented a major step forward in comparison with the competing self-assembly kits of the day.

The winning lot comes with a number of pieces, including the Apple-1 motherboard, a 6502 microprocessor, printed circuit board, three capacitors, heatsink, cassette board connector, 8K bytes of RAM, keyboard interface, firmware in PROMS, low-profile sockets on all integrated circuits, video terminal, and a breadboard area with slightly later connector.

Everything is contained in its original shipping box. The lot also includes a letter signed by "Steven Jobs."

The Apple-1 was shipped from the garage of Jobs's parents house. Christie's said it did not have data on how many of the devices were sold, but said that in April 1977, the price on the Apple-1 dropped to $475, and it was officially discontinued in October 1977 with the introduction of the Apple-II. The Apple-II was "a major advance with integrated keyboard, sound, a plastic case, and eight internal expansion slots," Christie's said.

The Apple-I is not the only tech-related item going up for auction today. Key papers from British computer scientist and wartime codebreaker Alan Turing will also be sold. Google announced Tuesday that it will contribute $100,000 so that Dr. Sue Black can try purchase them, but that might not be enough.

Dr. Black is a computer scientist at University College London and a key campaigner for Bletchley Park, where Dr. Turing worked. "The lot includes codebreaker Max Newman's copies of many of Turing's papers. Some of the papers have on them comments from Newman, a friend of Turing's who testified in his defence at his trial," Black said in a statement posted on the Google blog. "These papers belong at Bletchley Park, home of the codebreakers, and where these two codebreakers worked together side by side, helping to save millions of lives during World War II."

Dr. Black asked Google to help purchase the papers for Bletchley Park, "which we agree is clearly the right place to house them," Google said. The search engine giant will contribute $100,000, but given that Christie's estimates that the papers will bring in between $480,900 and $801,500, more funds are likely needed.

Dr. Black solicited donations on her Web site, and had collected a little over $32,000 prior to the auction's start, about 4 percent of the necessary funds. "While I'm more than happy for you to continue donating to support the amazing works of the Bletchley Park Trust, please be aware that funds received after this deadline will not form part of Bletchley Park's bid to buy Turing's papers," Dr. Black wrote on her site.

As of press time, the Turing auction was ongoing.
