The model 128K is the first product in the Macintosh family of computers. Apple Corporation introduced it in January 1984, after an intensive marketing campaign. “If computers are so clever, – one of the advertisements said, – isn’t it better to teach them to communicate with a person than to teach people to communicate with a computer?” Simultaneously with the official announcement of Macintosh, a 60-second advertising clip 1984, directed by the well-known Ridley Scott (Stranger), was shown on TV. The clip that cost $ 1.5 million, according to the legend, was shown only once, but it was enough: numerous mass media spread the video, inspired by Orwellian fantasies, free of charge, turning it into one of the most significant events in the history of television.

The Macintosh 128K was based on 32-bit microprocessor Motorola 68000 with clock speed of 8 MHz, had 128 KB of RAM, 64 KB of ROM, a one-way 400 KB 3.5-inch floppy drive, a built-in 9-inch black and white screen with graphics resolution of 512×342 pixels, was equipped, in addition to the keyboard, with a manipulator “mouse” and weighed 20 pounds (8 kg.).

Many things in the new computer were taken from the developments of the PARC research center of the company Xerox, 15 specialists of which in the early 1980s moved to work in Apple. It was thanks to the achievements of PARC that a system of “windows” on the screen, an interface based on symbolic images of actions, a device “mouse” appeared.

The first Macintosh was five times more expensive than the project specification required – $ 2495 instead of $ 500. But sales were very successful: in the first 9 months, 275,000 computers were sold. “Mac”, as the fans soon dubbed the new machine, brought Apple a grand success. With its appearance, the entire computer industry turned upside down. Owners of other types of computers envied the graphic means of “Mac” and the ease with which it was handled. Programs that allowed the use of “windows” and “mouse” in computers of other models, sold out like hot cakes.

However, very soon the users of the Macintosh 128K ran into the problem of too small amount of RAM, in conditions when the design of the model did not leave to expand it. Numerous complaints arose that prompted Apple to improve its product, and in the fall of the same 1984 the world was presented with a new “Mac” – Macintosh 512K (the Macintosh 128K was discontinued in October 1985).
