Cyrix 5x86-120GP. The Cyrix 5x86 is a line of x86 microprocessors designed by Cyrix and released on June 5 of 1995. [1] [2] [3] Cyrix, being a fabless company, had the chips manufactured by IBM. The line came out about 5 months before the more famous Cyrix 6x86. The Cyrix 5x86 was one of the fastest CPUs ever produced for Socket 3 computer systems.
While compatibility cards date back at least to the Apple II family, the majority of them were made for 16-bit computers, often to maintain compatibility with the IBM PC. The most popular of these were for Macintosh systems that allowed them to emulate Windows PCs via NuBus or PCI; Apple had released several such cards themselves. [1]
Many early microcomputers were available in Electronic kit form. Machines were sold in small numbers, with final assembly by the user. Kits took advantage of this by offering the system at a low price point. Kits were popular, beginning in 1975, with the introduction of the famous Altair 8800, but as sales volumes increased, kits became less ...
Cyrix 5x86 (M1sc) was a cost-reduced version of the flagship 6x86 (M1). Like Intel's Pentium Overdrive, the Cyrix 5x86 used a 32-bit external data bus. While AMD's Am5x86 was little more than a clock-quadrupled 486 with a new name, Cyrix's 5x86 implemented some Pentium-like features. Cyrix 6x86-P166
With the x86 naming scheme now legally cleared, other x86 vendors had to choose different names for their x86-compatible products, and initially some chose to continue with variations of the numbering scheme: IBM partnered with Cyrix to produce the 5x86 and then the very efficient 6x86 (M1) and 6x86MX lines of Cyrix designs, which were the ...
In 1995 IBM introduced a card, the "Enhanced S/390 MicroProcessor Complex", which supported IBM ESA/390 architecture on a PC-based system. [20] IBM's PC-related products evolved to support that as well, employing the card (IBM part number 8640-PB0) in the "IBM PC Server 330 in 1998 [21] [22] and the IBM PC Server 500 models. [23]

Products, services, and subsidiaries have been offered from International Business Machines (IBM) Corporation and its predecessor corporations since the 1890s. [1] This list comprises those offerings and is eclectic; it includes, for example, the AN/FSQ-7, which was not a product in the sense of offered for sale, but was a product in the sense of manufactured—produced by the labor of IBM.
