The 68-pin Very High Density Cable Interconnect (VHDCI) connector was introduced in the SPI-3 document of SCSI-3. The VHDCI connector is a very small connector that allows placement of four wide SCSI connectors on the back of a single PC card slot. Physically, it looks like a miniature Centronics type connector. It uses the regular 68-contact pin assignment.
VHDCI cables have also been used by NVidia as an external PCI Express 8-lane interconnect, and used in Quadro Plex VCS.
ATI Technologies is now using VHDCI connectors on the FireMV 2400 to convey two DVI and two VGA signals on a single connector, and ganging two of these connectors side-by-side in order to allow the FireMV 2400 to be a low-profile quad display card.
