My friend, the 1980s was an incredibly exciting decade for the world of computing! Innovations in microchip design led to incredible advances in computer processing power and capabilities. Bold entrepreneurs brought us new ways of interacting with computers through graphical interfaces and handy input devices like the mouse. Computer networking started bringing the world closer together. Let‘s dive in and explore the key developments that made this such a revolutionary decade for technology.

Microprocessors – The engines of innovation

The driving force behind the computer revolution of the 1980s was the accelerated pace of advancement in microprocessor technology. Intel, Motorola, AMD and others kept unveiling new microprocessors that were faster, more efficient, and more capable. This allowed computer designers to build increasingly powerful machines that found their way into businesses, schools, and homes.

Here are some of the most important microprocessor milestones of the decade:

  • Intel 8086/8088 – Launched in 1978/1979, this pioneering 16-bit processor established the x86 architecture that still powers most PCs today. The 8088 variant used in the 1981 IBM PC had a 8-bit external bus.
  • Motorola 68000 – With its sophisticated 32-bit internals, the 68000 powered advanced workstations from companies like Apple and Sun Microsystems. It was chosen for the Apple Lisa (1983) and Macintosh (1984).
  • Intel 80286 – Building on the 8086, the 80286 added protected mode and arrived in 1982. This enabled advanced multitasking OS capabilities, used in systems like the IBM PC/AT.
  • Intel 80386 – The 32-bit 80386 could run a staggering 5 million instructions per second (MIPS). Arriving in 1985, it unleashed the potential of GUI operating systems like Windows and OS/2.
  • Motorola 68020 – As the successor to the 68000, the 68020 pushed performance to 33 MHz and powered high-end Apple Macs and the Atari ST PC.

To give you an idea of the improvement, back in the 70s a top-end microprocessor might have managed 0.02 MIPS. But by the late 80s, the 80386 could hit 5 MIPS – a 250X increase in performance! This exponential growth meant that with each new chip, computers became dramatically faster and more capable.

Intuitive graphical interfaces

Another exciting shift in the 1980s was the move toward graphical user interfaces (GUIs) that made computers more intuitive and user-friendly. These used bitmapped displays, windows, icons, menus, and pointers to create an environment that was easier to visually process than walls of text.

The Xerox Alto workstation in the 1970s had pioneered some of these concepts. But it was the Apple Lisa in 1983 that brought them to the masses. The Lisa featured a GUI with windows, icons and menus. It came with a mouse rather than just a keyboard for navigation.

Apple took things even further in 1984 with the revolutionary Macintosh. Its interface set the template for GUIs that we still use today, with pull-down menus, scroll bars, overlapping windows and WYSIWYG design. This made computers usable for millions more people beyond just the hacker crowd.

Following Apple‘s lead, many other companies soon created their own graphical interfaces including:

  • Microsoft Windows 1.0 (1985) – Provided a GUI for IBM PC compatibles.
  • Commodore Amiga (1985) – Had an advanced GUI called Workbench.
  • Atari ST (1985) – Featured the GEM desktop.
  • Acorn Archimedes (1987) – Powered by Arthur OS.

By 1990 around 25% of personal computers shipped had a graphical interface. The tide was turning away from text-based systems like MS-DOS toward a visual computing experience.

Home computers become mainstream

Thanks to these twin innovations of more powerful microprocessors and intuitive interfaces, home computers moved from hobbyist curiosity to mainstream consumer product in the 1980s. After the 1977 Apple II kicked things off, easy to use and affordable machines from companies like Commodore, Atari and Sinclair sparked a home computer boom.

Here are some of the most notable home/personal computers that found their way into millions of households:

  • Commodore 64 (1982) – With a $595 price tag, the C64 featured 64KB RAM, high-resolution color graphics and quality sound. It became the best-selling single computer model ever, selling over 17 million units.

  • ZX Spectrum (1982) – British company Sinclair Research released their ZX Spectrum line with models ranging from £125 to £175. They helped spur mainstream home computing adoption in Europe.

  • Commodore Amiga (1985) – The Amiga stood out for its 32-bit Motorola 68000 CPU and impressive graphics and sound capabilities. It developed a loyal following among gamers and creative professionals.

  • Atari ST (1985) – Atari‘s sleek 16-bit ST line featured a Motorola 68000 CPU and built-in GEM GUI. It competed with the Amiga in applications like music sequencing.

  • Nintendo NES (1985) – Nintendo‘s 8-bit NES console introduced millions to home video gaming. It helped revitalize the industry after its earlier 80s slump.

This home computer boom also fueled rapid growth in the video game industry. Total annual revenues surged from just $100 million in 1983 to over $5 billion in 1990! An entire generation embraced digital entertainment and creativity through these amazing new machines.

Desktop publishing empowers users

In the mid-1980s, advances in microcomputers coupled with new laser printing technology gave birth to the revolutionary concept of "desktop publishing". This allowed individuals to use their PC to design and print professional quality documents easily right from their home or office.

Several key developments came together to make desktop publishing possible:

  • Laser printers – Fast bitmap laser printers like the Xerox Star (1981) and affordable Apple LaserWriter (1985) allowed great print results.

  • Desktop publishing software – Packages like Aldus PageMaker (1985) provided word processing features tailored to page layout and publishing.

  • Image editing – Early paint programs like MacPaint enabled manipulating scanned images and designs for inclusion in documents.

  • PostScript – Adobe‘s device-independent page description language allowed high quality printing from low-cost laser printers.

With these tools, anyone could self-publish newsletters, brochures, invitations and more at a fraction of the traditional cost and effort. It marked a huge step in empowering individuals and democratizing publishing.

Hardware & software milestones

Many innovative computers, peripherals and software programs that appeared in the 80s left lasting legacies:

By 1990 over 800,000 LAN nodes were installed globally, up from near zero in 1980! Networking would prove crucial in connecting PCs together and paving the way for the internet.

The meteoric rise of Microsoft

A little company called Micro-Soft formed by Bill Gates and Paul Allen in 1975 steadily grew throughout the 1980s to become the dominant PC software powerhouse.

Microsoft specialized in programming languages and productivity software for early PCs. Recognizing the potential of IBM‘s 1981 PC, Gates negotiated supplying the PC-DOS OS. This was based on Microsoft‘s QDOS acquisition.

As "PC compatible" clones took off, Microsoft smartly licensed MS-DOS to every hardware maker, earning royalties on every copy.

Other key milestones:

  • Microsoft Word & Excel – These MS-DOS apps became the standard office suite of the 1980s business world.
  • Windows 1.0 – Provided a crucial Graphical User Interface for DOS PCs to compete with Apple‘s Macintosh.
  • Microsoft Office – The 1989 release bundled install of Word, Excel and PowerPoint.

By the late 1980s Microsoft was well on its way to dominating the world of personal computing for decades to come.

The ups and downs of Apple

Apple Computer was incorporated in 1977 and exploded in popularity with its Apple II computer and later GUI-based Macintosh. However, in 1985 co-founder Steve Jobs was forced out by the board of directors.

With its visionary leader gone, Apple struggled with lack of direction. New hardware products like the PowerBook and Newton had novel features but failed to recreate the magic of the Macintosh.

Meanwhile in 1985, Jobs founded a new computer company called NeXT. The NeXT Computer focused on high-end educational and research markets. Despite brilliant engineering, high prices kept it from mass adoption.

By the early 1990s, Apple was in decline, IBM had outsourced PC manufacturing, and Microsoft controlled the industry. But the following decade would hold great change in store…
