IBM PC (1980s) Today we can’t do without a personal computer (PC) for a day, but have you ever thought about the first mass computer for a user? The IBM PC 5150 is the first mass-produced personal computer manufactured by IBM, released in 1981. The IBM 5150 includes an Intel 8088 processor. The RAM could be up to 256 kilobytes. At the same time, the cheapest version of the computer had a memory capacity of only 16 kb, expandable up to 64 kb.

Moreover, it was even possible to insert both adapters and connect two monitors at once, monochrome and color.
