Who Made the First PC?
The first personal computer (PC) was created by a small company named MITS (Micro Instrumentation and Telemetry Systems), and it was called the Altair 8800. Released in 1975, the Altair 8800 is widely regarded as the first commercially successful personal computer, sparking the home computing revolution.
What Was the Altair 8800?
The Altair 8800 was a microcomputer kit developed by MITS, which was founded by Ed Roberts. It was initially sold as a kit for hobbyists through the magazine Popular Electronics. The Altair 8800 was powered by the Intel 8080 microprocessor and featured a front panel with switches and LEDs for input and output. At the time, it was a groundbreaking product that made computing accessible to individuals outside of large corporations and research institutions.
Key Features of the Altair 8800
- Microprocessor: Intel 8080
- Memory: 256 bytes (expandable)
- Input/Output: Front panel switches and LEDs
- Price: Approximately $400 for the kit
Why Is the Altair 8800 Considered the First PC?
The Altair 8800 is considered the first PC because it was the first widely available computer that individuals could purchase, assemble, and program themselves. It marked a significant shift from the era of mainframe computers, which were large, expensive, and operated by specialized personnel. The Altair 8800’s affordability and accessibility inspired a generation of computer enthusiasts and played a pivotal role in the development of the personal computing industry.
