Home Computer historical development timeline by era

The transition from massive, industrial room-sized mainframes to the “home computer” was driven by the invention of the microprocessor in the early 1970s. 

The Pre-Home Era (1971–1976) 

Before “home computers” existed as off-the-shelf products, they were sold as DIY kits for electronics hobbyists. 

  • 1971: Intel releases the 4004, the first commercial single-chip microprocessor.
  • 1974: The MITS Altair 8800 is featured in Popular Electronics; it is widely considered the spark of the personal computer revolution.
  • 1976: Apple Computer is founded. The Apple I goes on sale as a hand-soldered board for $666.66.
  • 1976: MOS Technology releases the KIM-1, the first single-board computer kit. 

The “1977 Trinity” & Early Adoption

In 1977, three computers were released that targeted ordinary consumers rather than just hobbyists. 

  • Apple II: Features colour graphics and eight expansion slots, becoming a standard for schools and early home users.
  • Commodore PET 2001: The first “all-in-one” home computer with a built-in monitor and tape drive.
  • TRS-80 Model I: Sold through Radio Shack stores, making computers accessible on the high street for $399.
