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 (expensive) processing system from (less expensive) 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. ==700/X== These were the first X-Terminals HP produced, featuring a similar case to that of some HP 9000/300 (Motorola 68000-based) workstations. They were driven by a pretty obscure CPU combination, an Intel 186 with a TI DSP as video coprocessor. * CPU: 16 MHz Intel 80186 with a 60 MHz Texas Instruments DSP as video processor * RAM: 1MB on board, 9MB maximum; one slot takes up to 8MB modules of unknown type * Video RAM: Unknown * Maximum video resolution/color-depth: 1024×768/8-bit * I/O connectors: RS-232 serial, HIL and two PS/2 for keyboard/mouse devices, AUI and BNC 10 Mbit Ethernet connectors and VGA video connector * Expansion: Unknown 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「HP X-Terminals」の詳細全文を読む スポンサード リンク
