PS/ValuePoint 325T in use. These systems used standard Industry Standard Architecture (ISA) bus, SVGA graphics and IDE hard disks. Later models introduced VESA Local Bus and PCI.
The original IBM Personal Computer, with monitor and keyboard. 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.
The TBM instructions are all encoded using the XOP prefix. They are all available in 32-bit and 64-bit forms, selected with the XOP.W bit (0=32bit, 1=64bit). (XOP.W is ignored outside 64-bit mode.) Like all instructions encoded with VEX/XOP prefixes, they are unavailable in Real Mode and Virtual-8086 mode.
Industry standard ISA/PCI architecture, [1] first IBM machines with USB.Processors ranged from the 486DX2-50, 486SX-25, 486DX4-100 to the 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/ISA or PCI/ISA.
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 i486SX was a microprocessor originally released by Intel in 1991. It was a modified Intel i486DX microprocessor with its floating-point unit (FPU) disabled. It was intended as a lower-cost CPU for use in low-end systems—selling for US$258—adapting the SX suffix of the earlier i386SX in order to connote a lower-cost option.
80486SL. The Intel i486SL is the power-saving variant of the i486DX microprocessor. [1] The SL was designed for use in mobile computers. It was produced between November 1992 and June 1993.
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.
