This article deals with the history of research, design and development of the mini-computer family, microprocessors and micro-computers with the so-called SC - architecture (from Scientific Centre in Russian writing — abbreviated from ‘Nauchnyi Centr’ (НЦ — Научный Центр) and the based on them systems, created by the Zelenograd Microelectronics Centre in the first half of the 1970s. The «Electronica NC» family (“Электроника НЦ”) had a bus-modular structure, that enabled easy creation of various computation, control, and management systems. At the first development stage the family modules were based on integrated circuits with low and medium integration levels (ICs and MICs). At the second stage, those were BIC microprocessors, memory storages, and BICs based on basic matrix crystals (BMC - chips).
