  • Intel 486

    processor (Or “i486”, “iAPX 80486”, and “Intel DX4” but usually just “486”). A range of Intel CISC microprocessors which is part of the Intel 80×86 family of processors. The 486s are very similar to their immediate predecessor, the Intel 80386DX. The main differences are that the 486 has an optimised instruction set, has an on-chip […]

  • Intel 486dx

    processor One of Intel’s Intel 486 family of microprocessors (one of the last before the Pentium). The 486DX has a working built-in floating point unit (FPU). The Intel 486SX is effectively a DX with the FPU disabled. The DX has a pin to select the external data bus width (16 or 32). The Intel 487SX […]



  • Intel 486sx

    processor An Intel 486DX microprocessor with its floating-point unit disconnected. All 486SX chips were fabricated with FPUs. If testing showed that the CPU was OK but the FPU was defective, the FPU’s power and bus connections were destroyed with a laser and the chip was sold cheaper as an SX, if the FPU worked it […]

  • Intel 487sx

    processor A version of the Intel 486DX microprocessor with an extra pin, for use in the coprocessor socket of an Intel 486SX system. The 487SX provides the FPU which is missing in the 486SX. Although the 486SX is completely disabled when you install a 487SX, the 487SX design requires that you leave the 486SX in […]
