The Apple-1 computer was the device that kicked off our personal computing revolution, and now you can own one, complete with the rare first manual. But you might not want to make it your main machine: the Apple-1 motherboard hasn’t been powered up since 2005.

The Apple-1 sale is part of the online-only Seven Centuries of Science auction going on now at Christie’s. The auction house expects the Apple-1 to fetch between £300,000 and £500,000 ($459,795–$766,325). The auctions includes tech dating back to the 14th century, with items like an Enigma cipher machine used by Germany in WWII and an early wave-calculating machine from 1850.

“This curated sale charts the development of scientific instruments: beginning with the 14th century sundial, the story culminates with the dawn of home computing and the 1976 Apple-1, produced by Wozniak and Jobs in the garage of his parents’ house,” said Christie’s head of science and books, James Hyslop. “The revolutionary pre-assembled motherboard was the founding of what is now not just the largest computing company in the world, but the largest company.”

The earliest device in the auction was discovered by a metal detectorist last year. The 14th century horary quadrant is the oldest scientific instrument that Christie’s has ever presented. It was used as a sundial, but has unequal hours to measure the daylight left during different times of year. The opening bid for the heavily patinaed piece of tech is £50,000 ($76,632).

However, the Apple-1 is the star of the show. It was originally purchased in 1977 and has only had one other owner since then. When Apple came out with its next machine, it offered discounts to Apple-1 owners to return the machine and get the newer device at a discount. The older machines were destroyed, and now only about a quarter of the approximately 200 original machines are thought to exist. Of those left, 15 are in public collections, so very few are available to private collectors.

The auction runs until Oct. 29, so you’ll want to jump in on this sale soon if you want your hands on the history of computing that brought us to this moment in our technological world.
