7 Old Computers That Sell for Thousands on eBay

7 Old Computers That Sell for Thousands on eBay

That dusty desktop in the garage? It might be worth more than you think. Vintage computers are having a moment—collectors, tech historians, and even museums are paying top dollar for rare models. What once felt obsolete is now turning into serious resale cash.

Whether it’s nostalgia, rarity, or the beginnings of Silicon Valley history, these old machines are quietly racking up four- and five-figure sales on eBay and collector sites. Here are seven to look out for.

1. Apple I (1976)

This is the holy grail. Only about 200 were made, hand-built by Steve Wozniak and sold by Steve Jobs out of a California garage. If you find one—fully intact or even partially restored—it could be worth anywhere from $400,000 to over $1 million.

Even replica kits or manuals from that era are now collector items. But originals? Life-changing money.

2. Apple Macintosh 128K (1984)

The original Macintosh that changed computing forever. If it’s in working condition and includes the original keyboard, mouse, and manuals, prices on eBay regularly cross the $2,000–$5,000 mark.

Early production serial numbers or models signed by the development team can bring in even more.

3. Commodore 64 (1982)

It was the best-selling home computer of all time—but certain editions now fetch serious cash. A boxed, unused unit with all the accessories can bring in $1,000 or more. Rare versions, like early prototypes or promotional bundles, can exceed that.

Look for original boxes, floppy drives, and cartridges—these add value quickly for collectors who want the full experience.

4. IBM 5100 Portable Computer (1975)

Think of this as the “pre-PC.” The IBM 5100 came years before the IBM PC and is extremely rare. If you’ve got one in working condition, expect offers in the $10,000–$25,000 range depending on configuration and documentation.

They’re bulky, they’re heavy—and they’re gold to vintage tech buyers.

5. NeXT Computer (1988)

Created by Steve Jobs after leaving Apple, the NeXT Computer was where Tim Berners-Lee wrote the first web browser. It’s a cult piece of tech history. Working units—especially the cube models—can sell for $5,000 to $15,000.

If it comes with NeXTSTEP software or original documentation, expect bids from collectors, developers, and even museums.

6. Altair 8800 (1975)

This was the computer that inspired Bill Gates to write his first version of BASIC. A fully functional Altair 8800 with its original case, boards, and front panel lights can go for $10,000+. Even incomplete units and parts can bring in solid cash.

If you find one at an estate sale or tucked away in an old lab, don’t underestimate it—it’s tech history in a box.

7. Tandy TRS-80 Model I (1977)

RadioShack’s first personal computer still has a cult following. Early models with original cassette drives, keyboard units, and monitors can sell for $1,500 to $4,000, depending on condition and rarity.

The more complete the setup, the higher the value. Even boxed educational software from that era can sell on its own.

Obsolete Doesn’t Mean Worthless

Before you donate that old desktop or clean out your parent’s attic, take a closer look. Vintage computers—especially early Apple, IBM, and hobbyist models—are hotter than ever in the collector market.

Working or not, they tell a story about where tech came from. And in the right hands, that story is worth thousands.
