IBM PS/2
The Personal System/2 or PS/2 is IBM's second generation of personal computers. Released in 1987, it officially replaced the IBM Personal Computer, IBM PC, IBM Personal Computer XT, XT, IBM Personal Computer/AT, AT, and IBM PC Convertible, PC Convertible in IBM's lineup. Many of the PS/2's innovations, such as the 16550 UART (serial port), 1440 KB 3.5-inch floppy disk format, 72-pin SIMMs, #Keyboard/mouse, PS/2 port, and #Graphics, VGA video standard, went on to become standards in the broader PC market. The PS/2 line was created by IBM partly in an attempt to recapture control of the PC market by introducing the advanced yet Vendor lock-in, proprietary Micro Channel architecture (MCA) on higher-end models. These models were in the strange position of being incompatible with the hardware standards previously established by IBM and adopted in the IBM PC compatible industry. Most major PC manufacturers balked at IBM's licensing terms for MCA-compatible hardware, particularly the pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IBM 386SLC
The 386SLC is an Intel-licensed version of the 386SX (32-bit internal, 16-bit external, 24-bit memory addressing), developed and manufactured by IBM in 1991. It included power-management capabilities and an 8KB internal CPU cache, which enabled it to yield comparable performance to 386DX processors of the same clock speed, which were considerably more expensive. Known inside IBM as ''"Super Little Chip"'' for its initials, it was used in the IBM PS/2 35, 40 and 56 Series and in the IBM PS/ValuePoint 325T, but never gained much market share. This was mainly due to an agreement with Intel, in which IBM was not allowed to sell their CPUs if they were not part of a system or upgrade board. It was also marketed as an optional upgrade for 8086-equipped IBM PS/2 25 Series computers. Design and Technology Built with complementary metal oxide semiconductor (CMOS) technology, the IBM 386SLC had a 161-square millimeter die. It was available with clock speeds of 16, 20, and 25 MHz.

Intel 80486DX2
The Intel486 DX2, rumored as 80486DX2 (later rebadged i486DX2), is a CPU produced by Intel that was first introduced in 1992. The i486DX2 was nearly identical to the i486DX, but it had additional clock multiplier circuitry. It was the second CPU chip to use clock doubling, whereby the processor runs two internal logic clock cycles per external bus cycle. An i486 DX2 was thus significantly faster than an i486 DX at the same bus speed thanks to the 8K on-chip cache shadowing the slower clocked external bus. Both 25/50 and 33/66 MHz Intel486 DX2 CPU uses the 800 nm process technology. With the internal clock doubler CPU, it boosts overall system performance between 50 and 70 percent above the original Intel486 DX series. In other words, the 50-MHz Intel486 DX2 provides about 70 percent improvement over the 25-MHz Intel486 and about 30-percent improvement over the 33-MHz Intel486 CPU. The 50-MHz Intel486 DX2 CPU was rated at 40 Dhrystone MIPS. The 66-MHz Intel486 DX2 version ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ATI Technologies
ATI Technologies Inc. was a Canadian semiconductor industry, semiconductor technology corporation based in Markham, Ontario, that specialized in the development of graphics processing units and chipsets. Founded in 1985, the company listed publicly in 1993 and was acquired by AMD in 2006. As a major fabless semiconductor company, ATI conducted research and development in-house and outsourcing, outsourced the manufacturing and assembly of its products. With the decline and eventual bankruptcy of 3dfx in 2000, ATI and its chief rival Nvidia emerged as the two dominant players in the graphics processors industry, eventually forcing other manufacturers into niche roles. The acquisition of ATI in 2006 was important to AMD's strategic development of its AMD Accelerated Processing Unit, Fusion series of computer processors, which integrated general processing abilities with graphics processing functions within a single chip, which would become a popular option on computers in the foll ...

AMBRA Computer Corporation
Ambra Computer Corporation was a subsidiary of IBM. Created by Dr Richard Greame Ambra, it introduced a line of personal computers targeted at the home user, sold mainly through mail-order, first in Europe (1992), then in the USA (1993). Ambra had a volume production run of just a year or so; the line was discontinued in 1994 in favor of the IBM Aptiva (except for Canada, where it was not discontinued until 1996). 1994-07-29, NYTimes.com: Models * 386 * 486 * Achiever 2000 * Achiever 3000 * Achiever 4000 * Achiever 5000 * Achiever 7000 * Achiever 9000 * Achiever D * Achiever DP * Achiever S * Achiever T * Achiever Anthem * Achiever Hurdla/Sprinta ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IBM PS/1
The PS/1 (known in some European countries as the PS/1000) is a brand for a line of personal computers that marked IBM's return to the home market in 1990, five years after the IBM PCjr. It was replaced by the IBM Aptiva in September 1994. Position among IBM's PC brands The PS/1 line was created for new computer users and was sold in consumer electronics stores alongside comparable offerings from Compaq, Hewlett-Packard, Packard Bell, and others. American PS/1 models came with a modem installed so users could access online IBM help services, which were provided by partnerships with Prodigy (online service), Prodigy and Quantum Corporation, Quantum. Like the PCjr, the PS/1's name suggested a more limited machine than IBM's business line, the IBM Personal System/2, PS/2.

Intel P5
The Pentium (also referred to as the i586 or P5 Pentium) is a microprocessor introduced by Intel on March 22, 1993. It is the first CPU using the Pentium, Pentium brand. Considered the fifth generation in the x86 (8086) compatible line of processors, succeeding the i486, its implementation and microarchitecture was internally called ''P5''. Like the Intel i486, the Pentium is instruction set compatible with the 32-bit i386. It uses a very similar microarchitecture to the i486, but was extended enough to implement a dual integer instruction pipelining, pipeline design, as well as a more advanced floating-point unit (FPU) that was noted to be ten times faster than its predecessor. The Pentium was succeeded by the Pentium Pro in November 1995. In October 1996, the Pentium MMX was introduced, complementing the same basic microarchitecture of the original Pentium with the MMX (instruction set), MMX instruction set, larger caches, and some other enhancements.
