History of Personal Computer tech goes personal

Did you know the first personal computer didn’t even have a screen, mouse, or keyboard, and cost nearly as much as a used car? Back in 1971, the Kenbak-1 kicked off a revolution that would change the world forever. From those blinking lights and switches to the sleek laptops and smartphones we carry today, the journey of the personal computer is a story of constant innovation, creativity, and competition. Understanding the history of personal computer isn’t just about machines, it’s about how everyday people gained the power to learn, create, and connect like never before. Let’s dive into how it all began.

1. Early Beginnings of Computing (Pre-1970)

Long before we had personal computers on desks, large machines filled entire rooms. These were built mainly for governments and corporations.

1. 1943–1946: ENIAC

• The Electronic Numerical Integrator and Computer (ENIAC) was developed in the U.S. Army between 1943 and 1946.
• It was the first general-purpose, programmable computer.
• It used vacuum tubes and took up over 1,800 square feet.

2. 1951: UNIVAC I

• The UNIVAC I (Universal Automatic Computer) was the first commercially available computer.
• Delivered to the U.S. Census Bureau on June 14, 1951.
• It marked the beginning of electronic computing in business.

3. 1965: PDP-8 by DEC

• Digital Equipment Corporation launched the PDP-8 in March 1965.
• It’s often called the first mini-computer.
• Although not a personal computer, it cost around $18,000—much cheaper than mainframes, and brought computing to small labs and companies.

2. The First Personal Computers (1970–1977)

This era marked the beginning of computers made for individuals, not institutions.

1. 1971: Kenbak-1

• Released in early 1971, the Kenbak-1 is considered the world’s first personal computer.
• Created by John Blankenbaker, it sold for $750.
• It had only 256 bytes of memory and no monitor or keyboard.

2. 1973: Xerox Alto

• Developed at Xerox PARC in March 1973.
• It was the first computer with a graphical user interface (GUI), mouse, and Ethernet.
• However, it was not commercially sold, it was a research prototype.

3. 1975: Altair 8800

• Launched in January 1975 by MITS (Micro Instrumentation and Telemetry Systems).
• Cost $395 as a kit.
• Featured in Popular Electronics Magazine, it sparked the home computing revolution.
• Bill Gates and Paul Allen wrote Altair BASIC for it, this led to the creation of Microsoft.

3. The Boom of Home Computers (1977–1983)

This was the golden age of home computing. Several personal computers were launched for hobbyists, schools, and homes.

1. 1977: The “1977 Trinity”

Three major PCs launched in 1977:

• Apple II (April 1977): Created by Steve Wozniak and marketed by Steve Jobs.
• Commodore PET (January 1977): Known for its all-in-one design with monitor, keyboard, and tape drive.
• TRS-80 (August 1977): Sold through Radio Shack stores.

These were fully assembled and easier to use, unlike earlier kits.

2. 1980: VIC-20 by Commodore

• Released in 1980, the VIC-20 was the first computer to sell over 1 million units.
• Priced under $300, it was marketed as a “computer for the masses.”

3. 1981: Osborne 1

• Released in April 1981, the Osborne 1 was the first portable computer.
• Weighed 24 pounds and had a 5-inch screen.
• Priced at $1,795, it came with bundled software, an industry first.

4. IBM PC and Industry Standardization (1981–1985)

A major turning point came when tech giant IBM entered the market.

1. August 12, 1981: IBM 5150

• Known simply as the IBM PC, launched on August 12, 1981.
• Cost around $1,565.
• Used an Intel 8088 processor and ran MS-DOS, licensed from Microsoft.
• Open architecture: IBM encouraged third-party hardware and software. This created a compatible ecosystem.

2. 1982–1984: PC Clones

• Companies like Compaq, Dell, and HP started producing “IBM-compatible” computers.
• This lowered costs and increased adoption.
• The term “PC” became synonymous with IBM-style computers.

5. Rise of Microsoft and GUI Interfaces (1985–1995)

This era saw big improvements in software and user experience.

1. November 1985: Windows 1.0

• Microsoft released Windows 1.0 on November 20, 1985.
• It ran on top of MS-DOS and introduced simple windowed interfaces.

2. 1984: Apple Macintosh

• Launched on January 24, 1984.
• First mass-market PC with a graphical user interface (GUI) and mouse.
• Famous Super Bowl ad campaign set it apart from IBM PCs.

3. 1990: Windows 3.0

• Released on May 22, 1990, Windows 3.0 became a huge success.
• Added better graphics and memory support.
• Sold over 10 million copies in two years.
