Yes, that is an M7626 KA660 VAX 4000-200 CPU. The blue connector is the H3602 console panel connector, the bottom grey connector is the memory connector, and the top grey connector with two notches is the DSSI connector. Normally in a BA213 style chassis setup for DSSI disks there would be a white round cable that feeds down from the storage section on top which breaks out into the 50-pin plug to connect to the DSSI controller. It would look similar to the 26-pin cable for the TK70 tape drive, only the cable would be thicker and the connector wider. In your pictures there is 50-pin flat ribbon cable feeding down from the storage section. I'm not sure what that would be doing in your system, that doesn't look like something standard. -Glen
