1. Apple I (1976)
Estimated Value: $300,000 – $700,000+
The Apple I is not just a rare computer—it’s a piece of technological history. Designed and hand-built by Steve Wozniak in 1976, only 200 units were ever produced. Initially sold for $666.66, this computer came as a bare circuit board, meaning users had to provide their own case, keyboard, and monitor. Today, the Apple I is one of the most sought-after collectibles in the world, with prices reaching into the hundreds of thousands at auction.
- Why it’s valuable: It’s the first-ever product from Apple Inc., a company that went on to redefine technology. Its historical significance and extreme rarity make it a crown jewel in any collection.
Collectible Highlights:
- Original documentation and packaging can significantly increase its value.
- Fully operational models are exceedingly rare.
2. Commodore PET 2001 (1977)
Estimated Value: $2,000 – $5,000+
The Commodore PET 2001 was one of the first personal computers designed for the mass market, combining a built-in keyboard, monitor, and cassette drive in one sleek, futuristic package. Released in 1977, it was a groundbreaking machine that found success in schools and small businesses. Early versions of the PET, especially the original 2001-8 model, are highly prized by collectors.
- Why it’s valuable: The PET is one of the earliest all-in-one personal computers and a key player in the home computing revolution.
Collectible Highlights:
- Early models with the “chiclet” keyboard (a flat, calculator-style keyboard) are particularly sought after.
3. IBM 5100 Portable Computer (1975)
Estimated Value: $10,000 – $30,000+
The IBM 5100 is considered one of the first portable computers, though by today’s standards, its 55-pound weight makes it more of a desktop machine. Released in 1975, this computer predated the IBM PC and was aimed at scientists and engineers. With its built-in monitor, keyboard, and tape drive, the 5100 was a sophisticated and powerful machine for its time, but its high price tag meant it was out of reach for most consumers.
- Why it’s valuable: The IBM 5100 was a pioneering product and represents a key step in the development of portable computing.
Collectible Highlights:
- Units in working condition, especially with original accessories and documentation, fetch the highest prices.
4. Xerox Alto (1973)
Estimated Value: $30,000 – $100,000+
The Xerox Alto is often regarded as one of the most influential computers ever made, despite never being sold commercially. Developed at Xerox PARC in 1973, the Alto introduced the concept of a graphical user interface (GUI), complete with a mouse, icons, and windows. It was the precursor to many of the design elements later used in Apple’s Macintosh and Microsoft’s Windows. While only a few thousand units were built for research and academic use, the Alto’s impact on modern computing is immeasurable.
- Why it’s valuable: Its influence on personal computing design, coupled with its rarity, makes the Xerox Alto a highly coveted piece of computing history.
Collectible Highlights:
- Since the Alto was not widely available, any surviving units are extremely rare, especially those in working condition.
5. Altair 8800 (1975)
Estimated Value: $3,000 – $10,000+
The Altair 8800 is often credited with sparking the personal computing revolution. Released in 1975, the Altair was a kit-based computer that enthusiasts could assemble at home. It lacked many of the features we associate with modern computers, such as a monitor or keyboard, but it was one of the first affordable computers available to hobbyists. Bill Gates and Paul Allen wrote the first version of Microsoft BASIC for the Altair, marking the beginning of Microsoft’s journey.
- Why it’s valuable: As one of the first home computers and a key part of early Microsoft history, the Altair is a prized collectible.
Collectible Highlights:
- Fully assembled and operational models, as well as original kits, can fetch high prices, especially with complete manuals and software.
6. Apple Lisa (1983)
Estimated Value: $10,000 – $50,000+
The Apple Lisa was a groundbreaking computer for its time, introducing the world to the graphical user interface (GUI) and the concept of a mouse. Released in 1983, the Lisa was a commercial failure due to its high price, but it paved the way for the much more successful Macintosh. The Lisa is one of the most collectible Apple products, especially since relatively few were sold before it was discontinued.
- Why it’s valuable: The Lisa’s role in the development of user-friendly personal computers and its limited production make it a valuable collector’s item.
Collectible Highlights:
- The Lisa 1, the original version of the computer, is significantly rarer and more valuable than the Lisa 2, which was released later.
7. Sinclair ZX80 (1980)
Estimated Value: $1,000 – $2,500+
The Sinclair ZX80 is one of the earliest affordable home computers, particularly popular in the UK. Released in 1980, it was sold in kit form or as a fully assembled machine and was notable for its low price compared to other computers at the time. The ZX80 paved the way for the hugely successful ZX81 and Sinclair ZX Spectrum, both of which helped to popularize home computing in Europe.
- Why it’s valuable: The ZX80’s role in democratizing computing, along with its rarity (especially the kit versions), makes it a sought-after collectible.
Collectible Highlights:
- Original kit versions and units with original packaging are particularly prized.
8. Osborne 1 (1981)
Estimated Value: $1,500 – $3,000+
The Osborne 1 is recognized as the first commercially successful portable computer. Released in 1981, this “luggable” machine came with a built-in 5-inch screen and dual floppy drives, all packed into a briefcase-sized unit. The Osborne 1 was a game-changer in the business world, offering portability and affordability, although its bulky design and limited screen size seem primitive by today’s standards.
- Why it’s valuable: The Osborne 1 was a trailblazer in mobile computing, and its significance in the history of portable technology adds to its value.
Collectible Highlights:

Final Thoughts: How to Maximize Your Vintage Computer’s Value
If you own any of these rare and collectible vintage computers, consider the following tips to maximize their value:
- Condition is Key: Well-preserved, fully functional units fetch the highest prices. Make sure to keep original boxes, manuals, and peripherals if possible.
- Rarity Matters: Special editions or early production models are typically worth more.
- Provenance: Having a computer’s original documentation, such as sales receipts or user manuals, can significantly boost its value.
- Functionality: Vintage computers that are still in working condition are more desirable than non-working units, though even non-functional machines can still be valuable as display pieces or for parts.
Collecting vintage computers is not only a journey through the history of technology but also a potentially lucrative investment. Whether you’re a long-time collector or just starting out, these machines represent some of the most significant milestones in computing history, and their value is likely to continue rising as they become even rarer with time.
