Today, laptops are compact, powerful devices that fit in a backpack and weigh less than two kilograms. But it wasn't always like this. First laptop computers looked more like suitcases with electronics than the laptops we are used to. Their creation was made possible by revolutionary technologies in the 1970s and 1980s, when engineers tried to combine computing power with mobility.

In this article we will figure out When exactly did the first laptops appear?, which models are considered industry pioneers, and how they evolved to modern ultrabooks. You'll learn about little-known prototypes, commercial failures, and technological breakthroughs that changed the world of computing. And also why the first “portable” computers weighed as much as a small motorcycle and cost as much as a car.

1975–1981: Era of prototypes and experimentation

The idea to create laptop computer arose long before the appearance of the first production models. In 1968, an American engineer Alan Kay from the company Xerox PARC formulated the concept "Dynabook" - a notebook-sized device that could be used for learning and work. However, the technology to implement this idea simply did not exist at that time.

The first step towards modern laptops was IBM SCAMP (Special Computer APL Machine Portable), created in 1973. It was a microprocessor based prototype Intel 8008, weighing about 10 kg. The device had a monochrome display on 5 inches and a keyboard, but never went into mass production. His main goal is to prove that a portable computer is even possible.

  • 🔹 IBM SCAMP (1973) - the first prototype with a processor Intel 8008, weight ~10 kg
  • 🔹 Xerox NoteTaker (1976) - experimental device with a graphical interface, not released for sale
  • 🔹 Osborne 1 (1981) - the first commercially successful "portable" computer
⚠️ Attention: Many sources mistakenly call Osborne 1 "the first laptop". In fact it was laptop computer, but not a laptop in the modern sense - it could not be used on the lap, and its weight of 10.7 kg made it extremely uncomfortable to carry.

1981–1985: Commercial breakthrough and first “suitcase” PCs

The early 1980s became the era of the first serial laptop computers. They weren't laptops in the traditional sense, but they laid the foundation for future developments. The most famous model was Osborne 1, introduced in April 1981. He was worth it $1795 (about $5,500 in 2026 terms) and had:

  • 🖥️Display: monochrome 5 inches, 24 lines of 52 characters
  • 💾 Storage: two disk drives for 5.25" floppy disks (91 KB each!)
  • ⚡ Processor: Zilog Z80 with a clock frequency of 4 MHz
  • 🔋 Battery: missing - work only from the network

Despite the inconvenience, Osborne 1 was a hit, selling over 11,000 copies in its first year. Its success inspired competitors - already in 1982 it appeared Compaq Portable, the first IBM-compatible portable PC, and in 1983 Kaypro II with an improved keyboard and metal body.

1986–1991: Introduction of real laptops (clamshell format)

The true revolution occurred in 1986, when the company IBM released IBM PC Convertible - the first computer in the format "clamshell" (folding design with screen and keyboard). This device weighed “only” 5.5 kg and had:

  • 🖥️Display: Monochrome LCD screen 80x25 characters (no backlight!)
  • 💾 Storage: two disk drives for 3.5" floppy disks (720 KB)
  • ⚡ Processor: Intel 8088 (4.77 MHz)
  • 🔋 Battery: nickel-cadmium, operating time ~2 hours

However, the real breakthrough was Compaq SLT/286 (1988) - the first laptop with hard drive (20 or 40 MB) and processor Intel 80286. Its weight was 6.3 kg, and the price was about $6,000. It is this model that has become the standard for business users.

💡

If you get your hands on IBM PC Convertible or Compaq SLT/286, do not turn them on without first checking the capacitors! Over 30+ years they could swell and damage the board.

In 1989 Apple presented Macintosh Portable - the first portable Mac with active matrix display. Despite the innovative screen, the device weighed 7.2 kg and cost $6,500, making it a commercial failure. But NEC UltraLite (1988) weighed only 2 kg and became the first real ultraportable laptop.

1991–1995: Era of color screens and multimedia

The beginning of the 1990s was marked by two key events: the emergence color displays and standard PCMCIA (for connecting modems and other devices). In 1991 Toshiba released Toshiba T4400 - the first laptop with VGA resolution (640x480) and color screen. And in 1992 IBM presented ThinkPad 700, who became a legend thanks to:

  • 🖥️ Color screen 10.4 inches with permission 640×480
  • 🖱️ TrackPoint — red “pacifier” instead of a mouse (patent IBM)
  • ⚡ Processor: Intel 486 (33 MHz)
  • 🔋 Battery: Nickel-metal hydride, up to 4 hours of operation

1993 was a turning point: Apple released PowerBook Duo - a modular laptop that could be inserted into a docking station. A Compaq presented Compaq Contura Aero, which weighed only 1.8 kg and became the prototype of modern ultrabooks.

Why were the first color laptops so expensive?

Color LCD matrices of the 1990s were manufactured using technology active matrix, which required the precision production of thin-film transistors. There were up to 70% of defective screens, which drove up prices. For example, Toshiba T4700 (1993) with a color display cost $4,500 - almost the same as a used car.

Technical limitations of the first laptops: what users lacked

Despite being revolutionary, the first laptops had a lot of shortcomings that seem absurd today:

  1. Weight and dimensions: Even the “compact” models weighed 4–7 kg. For example, Compaq LTE (1989) had dimensions 32×25×6 cm - like a small suitcase.
  2. Autonomy: The batteries held a charge from 1 to 3 hours. At the same time, charging took up to 8 hours!
  3. Performance: Processors 8088/80286 were 100–1000 times slower than modern ones. For example, IBM PC Convertible performed operations at a speed of ~0.5 MIPS (today even a smartphone has ~100,000 MIPS).
  4. Data storage: Hard drives of 20–40 MB were a luxury. Most models relied on floppy disks 3.5 inches (1.44 MB).
  5. Displays: Monochrome screens without backlight required external lighting. Colors were dim and had terrible viewing angles.
⚠️ Attention: If you find an old laptop with nickel-cadmium (NiCd) battery, do not try to charge it with a modern charger! These batteries have a "memory effect" and may swell or leak if used incorrectly.

How the first laptops changed the world: 5 key consequences

The advent of portable computers revolutionized not only the IT industry, but also everyday life. Here are the five main changes they brought:

  • 💼 Mobile office: Journalists, managers and engineers had the opportunity to work on the road. For example, Kaypro II used to write articles right on the spot.
  • ✈️ Aviation and space: IBM 5100 was used by NASA to calculate shuttle trajectories, and GRiD Compass (1982) became the first laptop in space - it was taken on board the shuttles.
  • 🎓 Education: Universities have begun equipping students with laptops for programming and engineering calculations. For example, Osborne 1 came with built-in BASIC and educational materials.
  • 📠 Communications: The appearance of slots PCMCIA made it possible to connect modems and fax adapters, which made laptops a tool for remote communication.
  • 🎮 Games: Despite the weak graphics, Compaq Portable launched Microsoft Flight Simulator and text quests. This laid the foundation for future gaming laptops.

Interesting fact: the first laptop virus appeared in 1987. He became Lehigh, which affected the boot sector of floppy disks. It was distributed through the exchange of floppy disks between users IBM PC Convertible.

💡

The main difference between the first laptops and modern ones is that they were tools for professionals, not mass-produced devices. They were bought by companies, scientists and the military, not ordinary users.

Myths and misconceptions about the first laptops

There are many myths surrounding the history of portable PCs. Let's look at the most common ones:

Myth 1: "Osborne 1 was the first laptop."

Reality: This was the first commercially successful laptop computer, but not a laptop in the modern sense. It couldn't be used on your lap, and its 10.7kg weight made it more "portable" than mobile.

Myth 2: "The first laptops were slower than desktops."

Reality: Yes, but not always. For example, GRiD Compass (1982) with processor Intel 8086 (8 MHz) outperformed many desktop IBM PC of that time, working for 8088 (4.77 MHz).

Myth 3: "Apple invented laptops."

Reality: Apple really released innovative models (Macintosh Portable, PowerBook), but the first portable PCs were created IBM, Osborne And Compaq. Apple came to the market later, but offered revolutionary designs (for example, a trackpad in PowerBook 100).

Myth 4: "Early laptops didn't have hard drives."

Reality: Most pre-1988 models did rely on floppy disks, but there were exceptions. For example, IBM PC Convertible had an optional 10 MB hard drive, and Compaq SLT/286 (1988) - standard HDD 20 or 40 MB.

FAQ: Frequently asked questions about first laptops

🔍 Which laptop is considered the first in history?
