Emulation of the iskra delta partner computer

In the 1980s, the computer industry in Slovenia was at its peak of development, and nowadays its achievements are practicaly nowhere to be found. Preservation of the Slovene computer heritage is of great importance from several perspectives, from educational and research to preservation of the national identity. In this paper we present various activities that we carried out for the conservation of one of the most important Slovenian computers, the Iskra Delta Partner. In doing so, we focus primarily on creating a computer emulator, which involves emulation of the processor and several related devices. We created the emulator in the C programming language, thus enabling its efficiency and portability, while with the help of appropriate tools, it can also be executed within a Web browser environment. In the first part of the paper we discuss the basic concepts of emulation and briefly examine the emulated computer. In the main part we present the emulator, its construction, and give a detailed description of the emulated devices. © 2018 Electrotechnical Society of Slovenia. All rights reserved.
