The Apple Lisa was the Apple company’s first easily accessible consumer computer. While previous consumer-friendly computers required users to operate via a series of typewritten commands, the Apple Lisa had icons that users could select via a computer mouse!

Sadly, many Apple Lisa computers released in 1983 are now defunct due to age and use. But the one that sold for $94,949 in 2021 was still functional. It once belonged to Roger Wagner (a software designer who once worked for Apple)!

It’s also a rare version of the Apple Lisa, as it features dual floppy disk drives (known as the Twiggy configuration) on the righthand side of the device, next to the monitor screen. While this early Apple PC wasn’t one of the brand’s most popular releases, it’s still an iconic part of the Apple legacy.

Why Is It So Expensive?

Few Apple Lisa computers have survived into the 2020s, and it’s not challenging to understand why.

Only about 10,000 of these PCs were sold during the early-to-mid 1980s. Over time, as newer devices hit the market, many Apple Lisa owners likely tossed their computers in the trash, as electronics recycling programs weren’t popularized until much later.

Finding a still-functioning Apple Lisa is almost impossible. This one stuck around primarily because it belonged to an Apple software designer, Roger Wagner. This Apple computer’s rarity, coupled with its historical significance, makes it a valuable find.

4. Steve Jobs’s Original “Apple Computer A” Prototype – $677,196

For most of the 1990s, Apple computers remained far less popular than their Windows counterparts. But everything changed when Steve Jobs released the first iPod and iPhone models. Since then, Apple has become the main competitor to Windows-based devices, though their devices tend to be pricier than those featuring Windows operating systems.

Still, the story of Apple PCs and consumer-friendly devices stretches further back than the 1990s. In fact, Steve Jobs and his partner Steve Wozniak were creating prototype computers during the mid-1970s!

One of these, the “Apple Computer A” Prototype, sold for $677,196 when it went to auction in 2022.

Why Is It So Expensive?

Even though this prototype is just a rough chunk of motherboard, it’s worth a small fortune thanks to its historical significance. Without the creation of this prototype, Jobs and Wozniak might have never developed the first consumer-friendly Apple PCs.

3. Apollo Guidance Computer – $746,000

When Neil Armstrong and Buzz Aldrin landed on the surface of the moon in 1969, it was a moment that changed human history. But this feat wouldn’t have been capable without the help of a powerful onboard computer like the Apollo Guidance Computer.

This multi-module digital computer helped astronauts and mission control guide the Apollo spacecraft through space and onto the lunar surface. While this type of computer wouldn’t exactly appeal to the average computer user today (it used a calculator-like interface and display screen), it was an essential part of NASA’s ability to fly men to the moon and back.

The Apollo Guidance Computer sold at a Sotheby’s auction in 2021, garnering a hefty $746,000 from the final bidder. Originally, its maximum estimated sales price was $300,000, meaning it sold for more than twice the estimated value!

Why Is It So Expensive?

This computer is historically significant in several ways.

It was one of the first compact computers ever created, being smaller than a two-door refrigerator, unlike other computers available at the time. It also helped NASA astronauts complete their mission to fly to the moon!

Consequently, it’s a museum-worthy piece that will become more of a technological treasure with the passing decades.

2. Apple 1 Computer – $905,000

When you think about computers, you probably think about a computer tower, a monitor, and a keyboard. But at its core, all computers are essentially just motherboards with connections.

That’s certainly the case with the Apple 1 Computer, also called the Apple 1 Motherboard. This green bit of fiberglass might be the first Apple computer ever created, functioning as a prototype that gave way to the official Apple 1.

Although it’s essentially just an exposed piece of motherboard, it has connection ports that allow users to connect a keyboard and monitor. This strip of cutting-edge tech (cutting edge for its time) sold for $905,000 at a Bonhams auction in 2014, making it the priciest Apple computer in the world.

Notably, this classic desktop computer is more valuable than several of the most expensive laptops!

Why Is It So Expensive?

Apple is one of the world’s most successful and profitable technology companies, in no small part due to their consumer-friendly computers. While the first Windows PC debuted in 1985, Apple released its iconic Apple 1 way back in 1976.

Consequently, this prototype-like motherboard is a piece of history. This historical significance makes it irreplaceable and exceptionally valuable, hence its almost $1 million auction price.

1. Semi-Automatic Ground Environment System – $8 Billion

The most expensive computer is the Semi-Automatic Ground Environment System (SAGE). This computer system (consisting of 56 AN/FSQ-7 computers) spanned more than 20,000 square feet and cost approximately $8 billion to create. However, some estimates put the final cost at around $12 billion!

Although the SAGE computer is no longer operational, being decommissioned in 1984, it helped the North American Aerospace Defense Command (NORAD) monitor North American airspace for over two decades (starting in 1963). This system was vital during the Cold War, which officially ended in 1991.

Unlike modern computers, SAGE was massive. It required a ton of space to operate and was housed in a four-story building.

It also had several monitoring sites throughout the United States and Canada, allowing NORAD officials to get a “big picture” of the skies over North America, thus allowing them to track potential airborne threats (like missiles) over an incredible radius.

Why Is It So Expensive?

This computer (or rather, computer system) is the world’s most expensive because it featured cutting-edge technology, consisted of more than 50 AN/FSQ-7 computers, and was vital to helping NORAD monitor airspace over North America during the Cold War.

If this computer system failed to deliver, the US military wouldn’t have been able to warn the American people of incoming missile attacks, and it wouldn’t have been able to take a proactive response to stop those attacks. In short, this system was a crucial line of defense that needed to be flawless in every way, and that kind of technological perfection doesn’t come cheap.

What’s the Most Expensive Computer of All Time?

The most expensive computer in the world is the Semi-Automatic Ground Environment System (SAGE). Technically comprised of 56 computers, this massive system was built to help the North American Aerospace Defense Command (NORAD) monitor the airspace over the United States and Canada.

It took several years to build SAGE, with construction completed in 1963. The total cost of building the SAGE system is estimated at $8 billion, though the true cost could be as high as $12 billion.
