The first model in the series, the HP 2100A, was released in 1971, followed by the HP 2100S and HP 2100T, which were used by organizations like United States Department of Defense, United States Department of Energy, and National Aeronautics and Space Administration. The HP 2100 series was widely adopted by various industries, including healthcare, finance, and manufacturing, with notable users like Johns Hopkins University, University of California, Berkeley, and Carnegie Mellon University. The HP 2100 was also used in various international organizations, such as the United Nations, European Union, and World Health Organization.

● Hardware

The HP 2100 series was based on a 16-bit central processing unit (CPU) designed by Hewlett-Packard, which was also used in other HP systems like the HP 1000 and HP 3000, developed in collaboration with companies like Intel Corporation and Texas Instruments. The HP 2100 had a maximum memory capacity of 32 kilobytes (KB), which was expandable to 64 KB or more using external memory modules, similar to those used in IBM PC and Apple II. The system also featured a range of input/output (I/O) options, including RS-232 serial interfaces, IEEE 488 interfaces, and parallel interfaces, compatible with devices from manufacturers like Teledyne, Analog Devices, and National Semiconductor. Additionally, the HP 2100 was used with various peripheral devices, such as printers from Xerox and Hewlett-Packard, and disk drives from IBM and Seagate Technology.

● Software

The HP 2100 series ran a variety of operating systems, including the HP 2100 Operating System (OS), which was developed by Hewlett-Packard in collaboration with companies like Microsoft and Digital Equipment Corporation. The HP 2100 OS supported a range of programming languages, including BASIC, FORTRAN, and COBOL, which were also used on other systems like IBM System/370 and UNIVAC 1100/2200. The HP 2100 also supported various application software packages, such as word processing and spreadsheet programs, developed by companies like WordPerfect Corporation and Lotus Software. Furthermore, the HP 2100 was used with various database management systems, such as IBM DB2 and Oracle Database, and networking protocols, like TCP/IP and X.25.
