The higher performance comes from new technologies, including new processors, faster 16K RAM semiconductor memories, and a new operating system. If p 1000 COMPUTER SYSTEMS, first introduced llin late 1976,1 are designed to give the user a choice of preconfigured nucleus systems that are easy to use, easily adapted to user applications, accurately specified, and easily supported and maintained. Instead of having to build a system from a vast array of hardware assemblies and software modules, the user can choose a nucleus system that offers a tested and documented starting point for any application effort. HP 1000 Systems are based on HP 1.000 Computers (formerly 21MX ComputersJ and the real-time executive (RTE) operating system. Because the application areas for these systems are extremely varied and cannot be covered by a single system, a family plan was established, defining a range of systems suited to different applications. The family starts with a low-cost system able to run applications programs under RTE control and provides an economically sound path for expansion to larger systems. The expansion path not only allows for the conversion of the starter system to a more powerful member of the family but also allows for the interconnection of a large number of family members to form a network.2 With these capabilities, a user can solve almost any problem in almost any application area. New HP 1000 Systems Two new systems have now been added to the upper end of the HP 1000 family. These systems, Models 40 and 45, feature a new real-time executive operating system, RTE-IV, that manages up to 64 programs simultaneously and handles data arrays as large as two megabytes. The Model 45 System is based on a new version of the HP 1000 Computer, designated the F-Series.

Another new HP 1000 System, Model 25, uses the F-Series Computer but has a memory-based operating system, RTE-M. The HP 1000 Family The HP 1000 family now consists of the following …
