IBM Personal Computer
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 Philip Don Estridge in Boca Raton, Florida. Powered by an x86-architecture Intel 8088 processor, the machine was based on open architecture and third-party peripherals. Over time, expansion cards and software technology increased to support it. The PC had a substantial influence on the personal computer market; the specifications of the IBM PC became one of the most popular computer design standards in the world. The only significant competition it faced from a non-compatible platform throughout the 1980s was from Apple's Macintosh product line, as well as consumer-grade platforms created by companies like Commodore and Atari.

IBM PC Series
The Personal Computer Series, or PC Series, was IBM's follow-up to the IBM Personal System/2, Personal System/2 and IBM PS/ValuePoint, 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 Announced in October 1994 and withdrawn in October 2000, it was replaced by the IBM NetVista, apart from the Pentium Pro-based PC360 and PC365, which were replaced by the IBM IntelliStation.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 PC series was more business-oriented than the Aptiva line. Models x86-based PC 100 The PC 100 was a budget model, available only in selected markets. PC 140 The PC 140 was a budget model, available only in selected markets. PC Series 300 Industry standard ISA/PCI architecture, first IBM machines with USB. Processors ranged from the Intel 80486DX2, 486DX2-50, 486SX-25, Intel DX4, 486DX4-100 to the Pentium (brand), Pentium 200 and in case of the Models 360 and 365 the Pentium Pro. 486 models had a selectable bus architecture (SelectaBus) through a replaceable riser-card, offering the choice of either VESA Local Bus/Industry Standard Arc ...

IBM System/23 Datamaster
The System/23 Datamaster (Model 5322 desktop model and Model 5324 floor model) is an 8-bit_computing, 8-bit microcomputer developed by IBM. Released in July 1981, the Datamaster was the least expensive IBM computer until the far less expensive and far more popular IBM Personal Computer, IBM PC was announced in the following month. Description The Datamaster is an All-in-one PC, all-in-one computer with text-mode Cathode-ray tube, CRT display, keyboard, processor, memory, and two 8-inch floppy disk drives in one cabinet. The processor is an 8-bit Intel 8085 running at 6.14 MHz, with bank switching to manage 128 KB of memory. Available RAM was 32 KB (expandable to 128 KB), and the machine had four internal expansion slots. It could display 80 × 24 characters of text (each character with 8 × 14 pixels) with 128 possible characters, on a built-in 12" green phosphor CRT. The intention of the Datamaster was to provide a computer that could be installed and o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
