A. Lazarkiewicz, W. Balasiński · Mathematics of Computation · 1961
This paper presents the technical data, logic, and control organization of a simple experimental computer operating in the minus-two system. The principles for composing the instructions from elementary operations, the characteristics of minus-two computer arithmetic, and the logic of the arithmetic unit are briefly explained. The paper is divided into the following sections: 1, Introduction; 2, Fundamental Logical Circuits; 3, The Memory; 4, Block Diagram; 5, The Control Unit; 6, Coordination with Teleprinter; 7, Instructions; 8, Minus-Two System and Range of Numbers in the Computer; 9, The Adding Unit; 10, The Sign and Overflow Register; 11, Multiplication; 12, Acknowledgments.
