I think you mean VLB (Vesa Local Bus).

If you think that looks like a PCI slot added onto an ISA slot, well that's exactly what it is, although the pin connections are different. It is a 32 bit interface running at the processor's external (ie before multipliers) speed, and is connected directly to the processor.
While I am here, I may as well talk about MCA or micro-channel architecture. Sorry, can't find a picture.
It was developed by IBM, and was a 10MHz 32-bit bus. Unfortunately, it was incompatible with ISA architecture, and was also proprietary to IBM, so there was very little uptake by other manufacturers. Since it was only slightly faster than EISA, which was backwards compatible with ISA, this architecture soon died in the pc market, although IBM continued to use it for it's RS6000 series of mini-computers, probably to stop end-users buying cheap pc components.
