The HP Precision bus (also called HP-PB and HP-NIO) [1] is the data transfer bus of the proprietary Hewlett Packard architecture HP 3000 and later many variants of the HP 9000 series of UNIX systems. This bus has a 32-bit data path with an 8 MHz clock .
HP computer products which used HP-IB included the HP Series 80, HP 9800 series, [23] the HP 2100 series, [24] and the HP 3000 series. [25] HP computer peripherals which did not utilize the RS-232 communication interface often used HP-IB including disc systems like the HP 7935. Some of HP's advanced pocket calculators of the 1980s, such as the ...
HP 9815A. Chronologically, the models of the family were: HP 9810A, a keystroke programmable computer with magnetic cards and LED display, introduced in 1971, [1]; HP 9820A, introduced in 1972, was the first HP model that deals with algebraic input (not only RPN) [2] featured a high level language simpler than BASIC that was later named high performance language (HPL),
The PCI-X standard was developed jointly by IBM, HP, and Compaq and submitted for approval in 1998. It was an effort to codify proprietary server extensions to the PCI local bus to address several shortcomings in PCI, and increase performance of high bandwidth devices, such as Gigabit Ethernet, Fibre Channel, and Ultra3 SCSI cards, and allow processors to be interconnected in clusters.
It fit the same option cards as the 64100A and 64110A, and was connected via an IEEE-488 bus to a standard HP 9000 Series 300 workstation running the HP-UX operating system rather than using a specially designed workstation such as the 64100A and 64110A. The name "HP 64000-UX Microprocessor Development Environment" was used with these systems.
Through the 82169A HP-IL/HP-IB Interface, HP-IL controllers could be connected to instruments with an HP-IB (aka GPIB or IEEE-488) interface, or vice versa. There were also plans to make test equipment with IL interfaces, but apart from the somewhat popular 3468A multimeter, only a few devices were introduced before HP-IL itself became obsolete.
A HP-HIL connector for keybords next to a HP-IB connector on an HP9000-310 workstation The HP-HIL ( Hewlett-Packard Human Interface Link ) is the name of a computer bus used by Hewlett-Packard to connect keyboards, mice, trackballs , digitizers, tablets, barcode readers, rotary knobs, touchscreens, and other human interface peripherals to their ...
The HP-75C and HP-75D were hand-held computers programmable in BASIC, made by Hewlett-Packard from 1982 to 1986.. The HP-75 had a single-line liquid crystal display, 48 KiB system ROM and 16 KiB RAM, a comparatively large keyboard (albeit without a separate numeric pad), a manually operated magnetic card reader (2×650 bytes per card), 4 ports for memory expansion (1 for RAM and 3 for ROM ...
