Few people have heard of it, yet many consider John Blankenbaker's KENBAK-1 to be the first commercial personal computer.

Koss introduced these headphones over 40 years ago, and they remain affordable favorites to this day.

Apple II - Setting the Benchmark For Home Computing in the Late 1970s

Appleii

The splash made by the Apple 1 computer would have been a mere footnote in computing history if it had not been followed by the incredibly successful Apple II. This $1298 machine set the benchmark for serious home and office use in the late 1970s. It could accommodate a very respectable 48K of memory and initially relied on an external cassette recorder for program storage.

An external 143K floppy drive followed in 1978, making the Apple II one of the first home machine systems to include “standard” floppy disk storage (you could add two). By mid 1978 Apple was offering the Apple II Plus, which came with 48K standard.

Steve Wozniak’s design did many things right: it incorporated a user-friendly keyboard in an era when most machines offered a baffling front panel of lights and switches, it included bit-addressable color graphics, supported low-cost floppy drives, and included a good BASIC language interpreter.

By 1979, over 50,000 Apple II machines had been sold. But that was nothing compared to the success Apple was about to have because of an innovative piece of software named VisiCalc. It was the world’s first spreadsheet program, a prehistoric forerunner of programs like Microsoft Excel. VisiCalc was first released for the Apple II, giving a huge boost to business sales. By 1982, a stunning 750,000 Apple II systems had been produced.
