HP X-Terminals

Last updated

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.

700/RX

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:

All models have these base features in common:

Entria

The Entrias were the low-cost line of X-Terminals, featuring the same architecture as the 700/RX terminals, but in a plastic case the same style as the HP 9000/712 workstation. They are very small and quiet.

The Entrias were available in different video configurations, depending on the exact model:

Common:

Envizex

The Envizex were the successors to the 700/RX terminals, featuring the same flat pizzabox case and a slightly modified architecture with a faster version of the Intel i960 RISC CPU. They have a (very quiet) fan inside.

Three different series were available which featured different speeds of the CPU:

Common aspects:

Entria II

These were the successors of the low-cost Entria X-Terminals, keeping their HP 9000/712-style small footprint plastic case. The system architecture was changed completely and is shared with the later Envizex II terminals. It is based around a NEC R4300 CPU and PCI-based I/O devices.

Envizex II

These are the bigger brothers of the Entria II X-Terminals, driven by the same R4300 MIPS CPU and PCI I/O architecture. The case was redesigned, is very easy to open and does not have any fans, making the terminal rather quiet.

Software

These X-Terminals/stations run a proprietary operating system from HP — Netstation, formerly Enware, with some versions apparently based on VxWorks (probably those with RISC support).

This software runs on theoretically any Unix system, native support is available for HP-UX 10, HP-UX 11, IBM AIX and Solaris 2.x. A generic installation image is provided for other Unix flavors; this can be used to install the software via the provided installation shell script on for instance various Linux or BSD flavors.

Netstation Version 7.1

The older Enware/Netstation Version 7.1, HP product B.07.11, supports the following i960-based terminals:

It was downloadable from a public HP FTP service (hprc.external.hp.com/B.07.11/), which however was apparently discontinued. [1]

Read the included documentation and technical reference and refer to the installation instructions. Generally, a Unix server is needed from which the station can boot its kernel and load its X server. This is done via TFTP; the station can be managed locally via a configuration screen or remotely on the server via customizable configuration files.

Netstation Version 9.0

The most current available Netstation version is 9.0, HP product B.09.11. This version supports the newer MIPS-based X-Terminals:

Same as with the older Netstation software, version 9.0 was available from a HP FTP service, which was discontinued. (See above)

The newer X-Terminals (IIs) can boot in different ways, over a NFS mount, a SMB share or plain TFTP. Included in the Netstation software is a native Java environment which makes execution of local Java applets on the terminal possible.
