The D21 Data Processing System by Svenska Aeroplan Aktiebolaget, Sweden
IEEE Transactions on Electronic Computers, 1963The D21 data processing system design uses simple system structure and fast circuits plus flexible memory and is thus adapted to the use of advanced software and easy application to diverse fields. A survey is given of design objectives, background, and the hardware-software system.
