VESA Local Bus

VESA Local Bus (VLB) was developed by the Video Electronics Standards Association and introduced on the 486 platform in 1992. It was designed to address the bottleneck of the 16-bit ISA slot and was primarily used for video cards. Typical boards had 1 or 2 VLB slots available.

The VLB solution was heavily tied to the 486 architecture, and thus when Intel released the Peripheral Component Interconnect (PCI) BUS on their Pentium platform the VLB BUS began to quickly die out.
