Sotheby’s to Auction Working Apple-1 with Serial Number 01-0033

Auction house Sotheby’s is preparing to sell a unique lot—a working Apple-1 computer with serial number 01-0033. Created in 1976, this device is part of the first batch of 50 machines hand-assembled by Apple co-founder Steve Wozniak. These computers marked Apple’s first commercial products and laid the foundation for the company’s future.

The lot’s owner, Harry Sadler, purchased the Apple-1 from Byte Shop in 1976. In a video presented by Sotheby’s, he demonstrates the device’s startup and operation. Sadler noted using the computer for BASIC programming experiments and even returned it to the store for repairs, where he met Steve Jobs. Despite lacking prior experience, Sadler later joined Apple after the company acquired his startup, Siri Inc., where he worked.

The lot includes not only the computer but also original accessories: a cassette recorder, keyboard, monitor, user manuals, and software on cassettes. Valued at $300,000–$500,000, the lot reflects its historical importance and rarity.

As part of the 'History of Science and Technology' auction on July 15, other rare exhibits will be featured, including Steve Jobs’ NeXT computer and models like MITS Altair 8800 and Mark-8. The auction in New York will draw collectors and tech enthusiasts from around the world.
