The company's first PC related product was the PC Speeder, a device designed to increase the clock speed (and thereby the performance) of the 8086 processor. The company then began work engineering a motherboard to retrofit the soon-to-be-introduced Intel 386 processor on their existing 286 platform.
The VESA Local Bus (usually abbreviated to VL-Bus or VLB) is a short-lived expansion bus introduced during the i486 generation of x86 IBM-compatible personal computers.Created by VESA (Video Electronics Standards Association), the VESA Local Bus worked alongside the then-dominant ISA bus to provide a standardized high-speed conduit intended primarily to accelerate video (graphics) operations.
The Intel 486, officially named i486 and also known as 80486, is a microprocessor introduced in 1989. It is a higher-performance follow-up to the Intel 386 . It represents the fourth generation of binary compatible CPUs following the 8086 of 1978, the Intel 80286 of 1982, and 1985's i386 .
The Cyrix Cx486SLC is a x86 microprocessor that was developed by Cyrix.It was one of Cyrix's first CPU offerings, released after years of selling math coprocessors that competed with Intel's units and offered better performance at a comparable or lower price.
New versions of the Mustang muscle car will begin shipping next week and more than two thirds of the orders include the big, 5-liter V-8 engine, Ford said Friday. Demand for roaring engines ...
Like the later and more famous Cyrix Cx5x86, it is a hybrid CPU, incorporating features of a new CPU (the Intel 80486) while plugging into its predecessor's (386DX) PGA132 socket. It runs at speeds of 25, 33, and 40 MHz. [4] The 486DLC can be described as a 386DX with the 486 instruction set and 1 KB of on-board L1 cache added.
On the front of the unit there two dials underneath the PC-speaker to adjust the brightness of the screen and the volume of the PC-speaker. The PC-speaker in the Compaq Portable 486 is unique in that there is a 3.5 mm audio input jack on the side of the unit to allow a third party ISA sound card to pass through its audio output to the PC ...
The official Cyrix 5x86 website boasted about several features of the chip that were disabled by default in the final versions. The most controversial of these features was the branch prediction feature, which was enabled in the benchmarks results on the company website when comparing the chip to Intel's Pentium processor.
