โœฆ Synopsis


A minicomputer installation dedicated to c.a.d, is described. The economy and flexibility of such systems when incorporating comprehensive graphics facilities is stressed. Suitable operating systems are discussed, including an executive program to provide software simulation of three virtual computers (each virtual machine may then run under an independent operating system). Features of the graphical system software are outlined, including device and machine independence, flexibility, ease of use and economy. The applications programming philosophy required is described together with several interactive programs developed for use in electronics design. These programs, used by electronic engineers and research scientists over the past four years, illustrate the flexibility inherent in the system.
