The IBM Personal Computer XT (model 5160, often shortened to PC/XT) is the second computer in the IBM Personal Computer line, released on March 8, 1983. [1] Except for the addition of a built-in hard drive and extra expansion slots, it is very similar to the original IBM PC model 5150 from 1981.
The IBM Personal Computer, commonly known as the IBM PC, spanned multiple models in its first generation (including the PCjr, the Portable PC, the XT, the AT, the Convertible, and the /370 systems, among others), from 1981 to 1987. It eventually gave way to many splintering product lines after IBM introduced the Personal System/2 in April 1987.
IBM claimed the XT/370 reached 0.1 MIPS (when the data fit in RAM). In 1984, the list price of an XT/370 in its typical configuration was approximately $12,000 so compared favorably with IBM's own mainframes on a $/MIPS basis; for example, an IBM 4341 delivered 1.2 MIPS for $500,000. While it theoretically reduced demand on customers ...
The IBM Personal Computer (model 5150, commonly known as the IBM PC) 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 ...
The IBM PC AT came with a 192-watt switching power supply, significantly higher than the 130-watt XT power supply. According to IBM's documentation, in order to function properly, the AT power supply needed a load of at least 7.0 amperes on the +5 V line and a minimum of 2.5 amperes on its +12 V line.
IBM did introduce an upgraded bus in the IBM PS/2 computer that overcame many of the technical limits of the XT/AT bus, but this was rarely used as the basis for IBM-compatible computers since it required license payments to IBM both for the PS/2 bus and any prior AT-bus designs produced by the company seeking a license. This was unpopular with ...
The $1,495 list price was the lowest of seven compatibles with comparable configurations in a September 1985 InfoWorld chart, and under half the price of the $2,820 IBM PC. [10] Along with the Tandy 1000 and Epson Equity series, the Model D was one of the first IBM PC compatible computers to become popular for home use, due to its low price and ...
ES PEVM (ЕС ПЭВМ) was a Soviet clone of the IBM PC in the 1980s. The ES PEVM models lineup also included analogues of IBM PC XT, IBM PC AT, IBM XT/370.. The computers and software were adapted in Minsk, Belarus, at the Scientific Research Institute of Electronic Computer Machines (НИИ ЭВМ).
