Service manual

By convention, processors are placed in the right <REFERENCE>(XMI)
slots, beginning with slot 1 and extending to slot 6. Memories are placed in
the middle slots, from slot A to slot 5 and then slots B and C, and VAXBI
adapters are installed in the left side of the card cage, beginning with slot
E.
An attached vector processor must be in the slot to the left of the
<REFERENCE>(XRP) module. The slot to the left of the vector processor
can be used only for a memory module. Installing another kind of module
can damage the vector module. A second scalar, vector, memory trio may
be placed next to the first. See Section 5.3 for a discussion of configuration
rules related to scalar/vector pairs.
For performance reasons, the scalar processor of a scalar/vector pair should
not be made the primary processor when other scalar processors are in the
system.
