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).
