context_page_description: HP X-Terminals are a line of X terminals from Hewlett Packard introduced in the early- to mid-1990s, including the 700/X and 700/RX, Envizex and Entria, and the Envizex II and Entria II. They were often sold alongside PA-RISC-based HP 9000 Unix systems. The primary use case was connecting several graphical consoles to a single server or workstation to allow multiple users access the same processing system from terminal systems. These X-Terminals all allowed high-resolution, color-graphics access to the main server from which they downloaded their operating system and necessary program files. All models featured limited expandability, in most cases additional I/O options for peripherals and memory for more programs or local storage. HP did not use its own PA-RISC platform for these systems, the first design used an Intel CISC processor, while all later systems used RISC platforms, first Intel i960 and later the popular MIPS.
  These 1990s X-Terminals, together with offerings from many other vendors from that time, were precursors to thin computing: the use of small dumb front-end systems for I/O and a larger processing system as back-end, shared by many concurrent users.
context_section_description: These are the direct successors to the 700/X line of X-Terminals and changed the architecture significantly.
  They were the first in a line of terminals to be driven by an Intel i960 RISC CPU and introduced a case which also was used on later systems. They have a (albeit very quiet) fan.
  Several submodels were available, featuring different video-options:
  16Ca: 1 MB video RAM, max. 1028×768 resolution, 8-bit color-depth
  19Ca: 2 MB video RAM, max. 1280×1024 resolution, 8-bit color-depth
  14Ci/16Ci/17Ci: 1 MB video RAM, max. 1028×768 resolution, 8-bit color-depth
  19Mi: 0.2 MB video RAM, max. 1280×1024 resolution, monographics
  All models have these base features in common:
  CPU: 22 MHz Intel i960CA with 1KB instruction cache
  RAM: 2 MB on board, 34 MB maximum; two slots take each up to 16 MB 72-pin non-parity SIMMs
  I/O connectors: RS232 serial, HIL and two PS/2 for keyboard/mouse devices, parallel for printer, AUI and BNC 10 Mbit Ethernet and VGA video connector
  Expansion: slot for a Boot-ROM cartridge
