History of computer hardware in Bulgaria


This article describes the history of computer hardware in Bulgaria. At its peak, Bulgaria supplied 40% of the computers in COMECON. The electronics industry employed 300,000 workers, and it generated 8 billion rubles a year. Since the democratic changes in 1989 and the subsequent chaotic political and economic conditions, the once blooming Bulgarian computer industry almost completely disintegrated.

Computer models

In the 1980s, Bulgaria manufactured computers according to an agreement within the COMECON:

Mainframes

IZOT series and ES EVM series.

Personal computers

For example, the Pravetz-8M featured two processors, 64 KB DRAM and 16 KB EPROM.

Production facilities

The largest computer factory was some from Sofia, in Pravetz. Another big facility was the plant "Electronika" in Sofia. Smaller plants throughout the country produced monitors and peripherals, notably DZU — Stara Zagora made hard disks for mainframes and personal computers.
