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.
The new platform with Intel processor also include the new Intel 845MP Chipset, [5] and ATI Mobility Radeon 7500 video controller with 16 MB graphics memory, and up to 1 GB PC2100 RAM [6] (maximum according to IBM manual, but it has been reported to accept 2 GB of RAM [7] [8]) with 256 MB as standard memory.
The Model D was the first Korean-made PC to be sold in the United States, and at the time of its introduction, it undercut the price of similar IBM PC compatibles by $500. [9] 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 ...
Gekko is the IBM's custom central processor for the Nintendo GameCube game console. Based on a PowerPC 750CXe, it adds about 50 new instructions and a modified FPU capable of some SIMD functionality. It has 256 KiB of on die L2 cache, operates at 486 MHz with a 162 MHz memory bus, is fabricated by IBM on a 180 nm process. The die size is 43 mm 2.
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 ...
It was the fourth member of the IBM System/370 line of computers, [a] and was the first IBM computer to use semiconductor memory for its main memory instead of magnetic core memory. [4] It was described as being five times faster than the IBM System/360 Model 40. First shipments were scheduled for late summer of 1971. [1]
Like the original IBM PC, an IBM PC–compatible computer uses an x86-based central processing unit, sourced either from Intel or a second source like AMD, Cyrix or other vendors such as Texas Instruments, Fujitsu, OKI, Mitsubishi or NEC and is capable of using interchangeable commodity hardware such as expansion cards.
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.
