CI750 Computer Interconnect Interface
From Computer History Wiki
The CI750 Computer Interconnect Interface is the CI interface for the CPU/Memory Interconnect (CMI) bus of the VAX-11/750.
It connects to one CI node directly, or to multiple CI nodes using the SC008 Star Coupler.
It consists of:
- The CMI card L0009 - VAX-11/750 CCI (CMI Cluster Interconnect Module), that is placed into the VAX-11/750 CMI backplane.
- The CIPA (CI Port Adapter) Unit, made of:
- H9542 - 40" Medium System Cabinet Kit, containing:
- 70-20407 - CIPA Power Supply
- xx-xxxxx - CIPA Mounting Box (DEC part number still unknown), containing:
- 54-15555 - CIPA Backplane, containing:
- L0100 - ILI (I Link Interface Module), or
- L0118 - ILI (I Link Interface Module) for up to 32 Nodes
- L0101 - IPB (I Packet Buffer Module)
- L0400 - CDP (Data Path Module)
- 54-15555 - CIPA Backplane, containing:
- H9542 - 40" Medium System Cabinet Kit, containing:
The CI750 uses the same CIPA (CI Port Adapter) as the CIBCI - VAXBI CI Interface, 1st generation
The L0009 in the VAX-11/750 and the CIPA are connected using the 70-19602 - L0009 to CIPA Cable.
CI750 revisions are covered in the VAX-11/750 & VAX-11/751 Revision Control document.
