Abstract :
In 1965 MOBIDIC-B was acquired by the National Bureau of Standards for use in its computer research facility. It has been employed as both object and tool in numerous projects including intermachine communication, multi-programming, process control and research applications programming. During its tenure significant modifications have been made to its hardware configuration and instruction set. Its history is summarzed in Figure 1. Now that MOBIDIC-B is nearing the end of its useful life, it is fitting that we record the essential characteristics of this one-of-a-kind, but significant, machine.
