【NEC】 NEAC System 100

In August 1973, NEC marketed an ultra-small computer : the NEAC System 100. Nine types of basic systems were available for this machine -- ranging from billing to batch data processing and multitasking. This made it possible to provide the optimal system for various types of user work. The NEAC System 100, as this level of computer, was equipped with Japan's first communication control capability to enable easy online processing, and thus this machine could also be used as an outstanding terminal computer. As software, the system was equipped, for greater ease-of-use, with APLIKA (Application Library by Kit Assembling)for automatic generation of applications and a newly developed office processing language BEST(Beginner`s Efficient & Simple Translator).

LSI and MSI were used for computing elements and memory elements, which greatly improved both performance and reliability. The systems were equipped with a self-diagnosis function enabling early discovery of malfunctions and quick recovery. Equipment miniaturization and greater system economy were achieved by using the microprogram system throughout for instruction control, system control and input/output control.
