The PS/2 E or Energy (IBM 9533) is a member of the IBM Personal System/2 family of personal computers (PCs). It was the first Energy Star-compliant PC,[ attribution needed ] consuming very little power relative to other contemporary PCs, and made extensive use of recycled materials in its enclosure.
The PS/2 E featured an IBM 486SLC2 microprocessor with a 16 KB L1 cache that ran at 50 MHz on a 25 MHz system bus (the processor clock was double that of the system bus). [1] The processor's performance was dependent on the L1 cache containing the required instructions and data; there was no external L2 cache on the motherboard like on some other 486-based computers.
It featured an ISA bus for input/output, which accepted a single ISA option adapter with the use of a riser card. Depending on the sub-model number, it came supplied with either a special option adapter for four PC card PCMCIA slots, or a network interface card for Ethernet or Token Ring networks for use as a diskless workstation. [2] Additional options included several PCMCIA cards, a color LCD screen, and a color LCD touch-screen with a special version of OS/2.
The PC borrowed some components from IBM's ThinkPad laptops: including the 1.44 MB floppy disk drive and the hard disk drive. Its enclosure was composed of recycled plastics, and was designed to be easily recycled at the end of its service life. The power supply unit maximum power consumption was 24 watts, and was completely passively cooled, and lacked a fan for that reason. [1]
The PS/2 E featured a full-sized internal PC speaker, two SIMM sockets, and an extended bank of memory soldered directly to the motherboard. It featured 1 MB of video memory for the onboard XGA-2 graphics adapter, which was attached to the ISA bus instead of the usual MCA bus. Like all Personal System/2 computers, if a change in hardware is performed, the configuration must be updated with the use of the reference diskette (for example changing the memory size).
The Extended Industry Standard Architecture is a bus standard for IBM PC compatible computers. It was announced in September 1988 by a consortium of PC clone vendors as an alternative to IBM's proprietary Micro Channel architecture (MCA) in its PS/2 series.
Industry Standard Architecture (ISA) is the 16-bit internal bus of IBM PC/AT and similar computers based on the Intel 80286 and its immediate successors during the 1980s. The bus was (largely) backward compatible with the 8-bit bus of the 8088-based IBM PC, including the IBM PC/XT as well as IBM PC compatibles.
The IBM Personal Computer is the first microcomputer released in the IBM PC model line and the basis for the IBM PC compatible de facto standard. Released on August 12, 1981, it was created by a team of engineers and designers at International Business Machines (IBM), directed by William C. Lowe and Philip Don Estridge in Boca Raton, Florida.
The Intel 486, officially named i486 and also known as 80486, is a microprocessor. It is a higher-performance follow-up to the Intel 386. The i486 was introduced in 1989. It represents the fourth generation of binary compatible CPUs following the 8086 of 1978, the Intel 80286 of 1982, and 1985's i386.
The Tandy 1000 is the first in a line of IBM PC compatible home computer systems produced by the Tandy Corporation for sale in its Radio Shack and Radio Shack Computer Center chains of stores. Introduced in 1984, the product line was aimed at providing affordable but capable systems for home computing or education, with some of its Tandy specific features like graphics, sound and joystick port making it more appealing for home use.
PC Card is a parallel peripheral interface for laptop computers and PDAs. The PCMCIA originally introduced the 16-bit ISA-based PCMCIA Card in 1990, but renamed it to PC Card in March 1995 to avoid confusion with the name of the organization. The CardBus PC Card was introduced as a 32-bit version of the original PC Card, based on the PCI specification. The card slots are backward compatible for the original 16-bit card, older slots are not forward compatible with newer cards.
In computing, an expansion card is a printed circuit board that can be inserted into an electrical connector, or expansion slot on a computer's motherboard to add functionality to a computer system. Sometimes the design of the computer's case and motherboard involves placing most of these slots onto a separate, removable card. Typically such cards are referred to as a riser card in part because they project upward from the board and allow expansion cards to be placed above and parallel to the motherboard.
Micro Channel architecture, or the Micro Channel bus, is a proprietary 16- or 32-bit parallel computer bus publicly introduced by IBM in 1987 which was used on PS/2 and other computers until the mid-1990s. Its name is commonly abbreviated as "MCA", although not by IBM. In IBM products, it superseded the ISA bus and was itself subsequently superseded by the PCI bus architecture.
The Personal System/2 or PS/2 is IBM's second generation of personal computers. Released in 1987, it officially replaced the IBM PC, XT, AT, and PC Convertible in IBM's lineup. Many of the PS/2's innovations, such as the 16550 UART, 1440 KB 3.5-inch floppy disk format, 72-pin SIMMs, the PS/2 port, and the VGA video standard, went on to become standards in the broader PC market.
The IBM Personal Computer AT was released in 1984 as the fourth model in the IBM Personal Computer line, following the IBM PC/XT and its IBM Portable PC variant. It was designed around the Intel 80286 microprocessor.
Chips and Technologies, Inc. (C&T), was an early fabless semiconductor company founded in Milpitas, California, in December 1984 by Gordon A. Campbell and Dado Banatao.
The MIPS Magnum was a line of computer workstations designed by MIPS Computer Systems, Inc. and based on the MIPS series of RISC microprocessors. The first Magnum was released in March, 1990, and production of various models continued until 1993 when SGI bought MIPS Technologies. SGI cancelled the MIPS Magnum line to promote their own workstations including the entry-level SGI Indy.
The Sun386i is a discontinued hybrid UNIX workstation/PC compatible computer system produced by Sun Microsystems, launched in 1988. It is based on the Intel 80386 microprocessor but shares many features with the contemporary Sun-3 series systems.
The Compaq Presario 1200 was a line of notebook computers produced between 1998 and 2000 by Compaq as part of Compaq Presario line.
The Personal Computer Series, or PC Series, was IBM's follow-up to the Personal System/2 and PS/ValuePoint. Announced in October 1994 and withdrawn in October 2000, it was replaced by the IBM NetVista, apart from the Pentium Pro-based PC360 and PC365, which were replaced by the IBM IntelliStation.
The Commodore PC compatible systems are a range of IBM PC compatible personal computers introduced in 1984 by home computer manufacturer Commodore Business Machines.
The DECpc AXP 150, code-named Jensen, is an entry-level workstation developed and manufactured by Digital Equipment Corporation. Introduced on 25 May 1993, the DECpc AXP 150 was the first Alpha-based system to support the Windows NT operating system and the basis for the DEC 2000 AXP entry-level servers. It was discontinued on 28 February 1994, succeeded by the entry-level Multia and the entry-level and mid-range models of the AlphaStation family. The charter for the development and production of the DEC 2000 AXP was held by Digital's Entry Level Solutions Business, based in Ayr, Scotland.
The Personal System/2 Model 30 and Personal System/2 Model 30 286 are IBM's entry-level desktop computers in their Personal System/2 (PS/2) family of personal computers. As opposed to higher-end entries in the PS/2 line which use Micro Channel bus architecture, the Model 30 features an Industry Standard Architecture bus, allowing it to use expansion cards from its direct predecessors, the PC/XT and the PC/AT. The original PS/2 Model 30, released in April 1987, is built upon the Intel 8086 microprocessor clocked at 8 MHz and features the 8-bit ISA bus; the Model 30 286, released in September 1988, features the Intel 80286 clocked at 10 MHz and includes the 16-bit ISA bus.
The Personal System/2 Model 50 is a midrange desktop computer in IBM's Personal System/2 (PS/2) family of personal computers. First released in April 1987, the Model 50 features an Intel 80286 processor running at a clock speed of 10 MHz. In June 1988, the PS/2 Model 50 received an update in the form of the Personal System/2 Model 50 Z, which offered faster RAM, eliminating the insertion of wait states endemic to the original Model 50 and increasing system performance. The Model 50 was the best-selling line of PS/2 for several years, IBM selling over 440,000 units in the first year of its availability.
