The '''CI780 Computer Interconnect Adapter''' (sometimes referred to by the acronym, '''CIA''') provided a high-performance [[Computer Interconnect]] interface for the [[VAX-11/780]] and other machines with a [[Synchronous Backplane Interconnect]]. It connects to one CI node directly, or to multiple CI nodes using the [[SC008 Star Coupler]]. Using the CIA, information can be transferred at up to 70 Mbits per second with other [[VAXcluster]] components.

The DR780 was implemented on four [[DEC card form factor|extended hex]] cards, which mounted in a custom 6-slot [[backplane]] ([[DEC part number]] 70-17654); the backplane mounted in one 'Option Panel Space' in the [[Central Processing Unit|CPU]] [[cabinet]]. The boards were:

{| class="wikitable"
! Slot !! Board !! Acronym !! Function
|-
| 1 || L0104 || ISI || SBI Interface Module
|-
| 2 || L0102 || IDP || Data Path Module
|-
| 3 || L0101 || IPB || Packet Buffer Module
|-
| 5 || L0100 || ILI || Link Interface Module
|}

Two backplane slots (4 and 6) are unused.
