HITAC M-260H

The high-end models, the M-280H and M-260H, were based on technology developed for the M-200H, and they achieved higher levels of performance and functionality by using newly developed technology, such as world leading logic-in-memory, 4Kbit/7ns high-speed bipolar memory, 550/1500gate LSI and platters which increased the degree of integration to 18 levels. Due to their outstanding cost-performance, these models were exported in large numbers to Europe and the US, where they enjoyed an outstanding reputation. For scientific and engineering calculations, the M-280H was equipped with high-speed arithmetic mechanisms and a built-in array processor.
