In October 1979 the State Committee for Science and Technical Progress (SCSTP) contacted the Institute of Technical Cybernetics and Robotics (ITCR) with the task to "create a small computer based on microprocessors". The development of the computer was undertaken by a team led by Ivan Marangozov and including Kancho Dossev, Georgi Zhelyazkov and Petar Petrov.

The first three experimental units of the computer, which was called IMCO-1 (Individual Micro COmputer 1), were completed in late 1980 and approved by SCSTP. They were based on a little-known foreign model with Intel 8080 8-bit microprocessor. The computer had a built in BASIC and instead of having floppy disk drives, a cassette tape recorder was used as external memory. In 1981 The experimental base of ITCR produced around 50 units from this computer. They were given to institute and university laboratories to get acquainted with the capabilities of the personal microcomputers.
In the same year a robot controlled by IMCO-1was demonstrated at Robotics Forum in England. The decision to controll a robot by a microcomputer was a novelty at that time. It reduced costs and simplified maintenance compared with commonly used minicomputers to control robots.

The last part of the guide lists the software products, distributed by the Microprocessor systems Pravetz.

As part of the documentation for Bulgarian 8 inch floppy disk drive model ISOT 5071E / ES 5074 we add C13.060.216 TO (Technical Description) and C13.060.216 TS (Table of Signals).
