1.7 MS670-BA Memory Specifications
The MS670-BA is a 32-Mbyte memory module that provides memory
expansion for
the KA.670-AA/-BA CPU module. The MS670-BA modules
interface with the CPU through the MS670 local memory interconnect.
You
can use up to four MS670-BA modules in the VAX 4000 Model 300
system.
Operating system support and diagnostic support are the same as for the
KA670 CPU module, as listed in Section 1.6.
