HP 2100

An HP 2116C.

The HP 2100 is a series of 16-bit minicomputers produced by Hewlett-Packard from the mid-1960s to the early 1990s. It was the first computer produced by HP and the first of their products to use an integrated circuit. The series was quite popular for business use, however, the inclusion of a BASIC interpreter meant that many games were programmed on the platform. Most of the initial models had a 10 MHz clock with a 1.6 microsecond cycle time.

Models

Released	Model	Notes
1966-11-??	2116A	4k words, expandable to 8 internal or 16 external.
1967-11-??	2115A	Cost-reduced version of the 2116A. 8 MHz, fewer I/O slots, external power supply.
1968-09-??	2116B	Added optional 32k words as external memory.
1968-10-??	2114A	Cost-reduced version of the 2116A, but easier to work with than 2115A which it replaced.
1968-11-??	2000A	An 8k 2116B running HP Time-Shared BASIC (up to 16 users).
1969-11-??	2114B	Cost-reduced version of the 2114A.
1970-10-??	2116C	Added optional 32k words as internal memory.
1970-10-??	2114C	Cost-reduced version of the 2114B. Max of only 16k words.
1971-??-??	2100A	4k words, expandable to 32.
1973-??-??	2100S	A 2100A with optional floating-point processor.

Each of the 2116 models (A-F) also included an equivalent 2000 model which included BASIC. Each 2000 used the 2116 as the main CPU and a 2114 as a terminal server.

Spinoff models include the 21MX series started in 1972, the several 1000 series which started in 1977 and were developed into the 1990s.

The computers in the 2000 series could run HP Time-Shared BASIC, the first BASIC interpreter to support time-sharing. The popularity of the platform meant that a lot of people in the 1970s had access to it, so a lot of programs were written for it. It was also the primary variant of BASIC used by the People's Computer Company magazine which published a lot of BASIC code and helped increase its popularity.

Most of the BASIC games made in the 1970s had an HP 2100 port and several were first developed on the HP 2100 like the first Star Trek game and the original Oregon Trail game.

Few game databases specify HP 2100 titles, and often group all mainframe games together.
