Correct, but bear in mind that there are 4 versions of the MSV11-J; the
-JB and -JC versions have different ASICs and don't support QBus CPUs.
Specifically, they don't support block-mode transfers and don't work
properly even as PMI memory except in an 11/84, while the -JE and JD
versions support everything. Bill would want the -JD (2MB) version (the
-JE version is 4MB so too big).
