VESA Local Bus: History & Standards

The VESA Local Bus (usually abbreviated to VL-Bus or VLB) is a short-lived expansion bus introduced in 1992 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…
