ISA (Industry Standard Architecture) was introduced in 1981 and was the primary expansion slot in IBM-compatible computers until the mid-1990s. While most modern computers no longer use ISA, it is still found in some older systems and embedded applications. EISA (Extended Industry Standard Architecture) was introduced in the late 1980s as a faster replacement for ISA, but it was quickly replaced by the faster and more versatile PCI bus, and is no longer in use. VL-bus (VESA Local Bus) was a short-lived expansion slot introduced in the early 1990s as a faster alternative to ISA, but it was quickly superseded by PCI. MCA (Micro Channel Architecture) was a proprietary expansion slot used in IBM's PS/2 line of computers, but it was never widely adopted and has been largely forgotten.
