【Oki-Univac】 OUK9000

The OUK9000 Series was a small/mid-size system employing devices which had still not been developed in Japan at the time -- such as monolithic ICs and plated wire memory. It was a computer incorporating a new design concept called interlinking, and the hardware and software were built not only to ensure compatibility from low-end models to high-end models, but also to enable low-end models to be used as is, as if they were input/output devices for high-end models. The biggest feature of the OUK9400, which was completed in 1967, was that it was a mass storage oriented system which made maximal use of a high-speed (156KB/second) magnetic disk unit. The series also used a true disk operating system based on the multiprogram system.
