A rare, working 1977 Apple-1 computer, known as the "Neumark" computer, is expected to fetch at least $300,000 at an RR Auction sale. This particular Apple-1, from the company's second batch of 50 machines, is housed in a modified Smith-Corona typewriter case and was recently restored to working condition.

Apple originally sold the Apple-1 as a circuit board, requiring buyers to supply their own components and enclosure. The "Neumark" machine is notable for still being functional within its unique case, which also includes surviving documentation. RR Auction's estimates are subject to bidding competition.

The auction, featuring Steve Jobs memorabilia and early Apple hardware, also includes a factory-sealed 4GB first-generation iPhone and a P68 "Stealth iPod" prototype, each estimated at around $50,000. Other items include a Jobs-signed check for over $25,000 and his eighth-grade science fair project.

This event highlights the significant historical and monetary value placed on early computing technology and Steve Jobs's legacy, with the Apple-1 potentially costing as much as 275 iPhone 17 Pros.
