The History of PC Hardware, in Pictures

We all use personal computers, and we all take them for granted in our everyday lives. It’s easy to forget that PCs have only been around for a couple of decades, and initially were nowhere near the powerhouses we have on our desks today.

For example, did you know that the first “portable” computer weighed 25 kg (55 lb) and cost close to $20,000? Or that the first laser printer was big enough to fill up most of a room? Or even, that you basically had to build the first Apple computer yourself?

This article takes a look at the time when the computer equipment we now take for granted was invented, and what it looked like back then.

The First Computer Mouse

The first computer mouse was invented in 1963 by Douglas Engelbart at the Stanford Research Institute. (He is also one of the inventors of hypertext.) The first mouse used two wheels positioned at a 90-degree angle to each other to keep track of the movement (see picture below). The ball mouse wasn’t invented until 1972, and the optical mouse was invented circa 1980, although it didn’t come to popular use until much later.

Douglas Engelbart never received any royalties for his invention and his patent had run out by the time the mouse became commonplace in the era of home PCs.

The First Trackball

The trackball was actually invented 11 years BEFORE the mouse, in 1952. It was invented by Tom Cranston and Fred Longstaff as part of a computerized battlefield information system called DATAR, initiated by the Canadian Navy. It used a standard five-pin bowling ball as its trackball, which is smaller than the more common 10-pin bowling ball.

The First Portable Computer

Well, perhaps that should be “movable” computer… The IBM 5100 Portable Computer was introduced in 1975, weighed 25 kg (55 lb), was the size of a small suitcase and needed external power to operate. It held everything in the same unit, packing in a processor, ROM (several hundreds of kilobytes) and RAM (16 – 64 KB), a five-inch CRT display, keyboard, and a tape drive, which was an amazing feat at the time. It also came with built-in BASIC and/or APL. The different models of the IBM 5100 sold for $8,975 – $19,975.

IBM 5100 was introduced to the public as the first portable computer in 1975. 20 years earlier—in 1955—IBM produced its first commercial computer, model 702. Check our Gallery of Early Computers (1940s – 1960s).

The First Laptop Computer

The first laptop computer (or notebook) was the Grid Compass 1100 (called the GRiD) and was designed in 1979 by a British industrial designer, Bill Moggridge. The computer didn’t start selling until 1982, then featuring a 320×200 screen, an Intel 8086 processor, 340KB of magnetic bubble memory (a now obsolete, non-volatile memory type), and a 1200 bps modem. It weighed 5 kg (11 lb) and cost $8,000 –$10,000. The GRiD was mainly used by NASA and the US military.

The First IBM PC

The IBM Personal Computer was introduced in 1981 as the IBM 5150. The platform became so pervasive in the 80s that although the term “personal computer” had been in use since the early 70s, a PC became synonymous with an IBM PC-compatible computer.

During its development, the IBM 5150 had been internally referred to as “Project Chess” and was created by a team of 12 people headed by Don Estridge and Larry Potter. To speed up development and cut costs, IBM had decided to use off-the-shelf parts, something they normally wouldn’t do.

The first IBM PC had an Intel 8088 processor, 64KB of RAM (extendible to 256KB), a floppy disk drive (which could be used to boot the computer with a rebranded version of MS-DOS (PC-DOS)), and a CGA or monochrome video card. The machine also had a version of Microsoft BASIC in ROM. On the first IBM PC, the optional 10MB hard disk drive could only be installed if the original power supply was replaced (the original one was too weak).

The First Apple Computer

The first Apple personal computers (Apple I) were designed and hand-built by Steve Wozniak. The Apple I went on sale in 1976 for the price of $666.66. Only about 200 units were produced. The Apple I was basically just a motherboard with a processor, a total of 8KB of RAM, a display interface, and some additional functionality. To have a working computer, the buyer would have to add a power supply, a keyboard, and a display (and a case to keep mount it all in).

In 2018, Apple claimed to be the first trillion-dollar company. Check our article on how Apple reinvented the laptop.

The First RAM

Arguably the first (writable) random access memory was Magnetic Core Memory (also called Ferrite-Core Memory) and was invented in 1951 as a result of work done by An Wang at Harvard University’s Computation Lab and Jay Forrester at MIT.

Core memory was a family of related technologies that used the magnetic properties of materials to give them a similar functionality to transistors. They stored their information using the polarity of tiny, magnetic ceramic rings with wires threaded through them. Unlike today’s RAM, core memory could keep its information even after the power was turned off.

Core memory was common until it was replaced by integrated silicon RAM chips in the 1970s. The “core” in core memory is why a memory dump is called a “core dump” even today.

The First Hard Disk Drive

The IBM Model 350 Disk File was the first hard disk drive and was part of the IBM 305 RAMAC (Random Access Method of Accounting and Control) computer that IBM started delivering in 1956 (mainly intended for business accounting). It had 50 24-inch discs that together could store about 4.4MB of data. The Model 350 spun at 1200 rpm, had a data transfer rate of 8,800 characters per second and an access time of approximately one second.

The First Laser Printer

The laser printer was invented by Gary Starkweather at XEROX in 1969. His initial prototype was a modified laser copier where he had disabled the imaging system and introduced a spinning drum with eight mirrored sides. The first commercial implementation of a laser printer didn’t happen until IBM released the IBM model 3800 in 1976. It could pretty much fill up a room on its own and had a speed of 20,000 lines per minute. This machine was mainly used for high-volume documents (for example, preparing bank statements).

The First Web Server

And since the Web is such an integral part of today’s computer experience, we couldn’t help but include another first; the first web server was a NeXT workstation that Tim Berners-Lee used when he invented the World Wide Web at CERN. The first web page was put online on August 6, 1991.

The computer had a note on it that said, “This machine is a server. DO NOT POWER IT DOWN!!” Understandable, considering that if you had shut it down in the early days you would have shut down the entire WWW.


Above: The web server that powered the first web pages on the WWW. Note the sticker with the warning to not turn it off.

It’s amazing how much has happened in the PC industry in just a few decades. Just imagine what things will be like 30-40 years from now…
