MVPG is not a fully-documented instruction.  Only its behavior from
the viewpoint of the virtual-address-space program is described.
Extensions to the page-table-entry format and such to support mapping
pages into expanded storage are not in the Principles of Operation.
Therefore, I don't see how Dave Weintraub or anyone else for that
matter can tell whether MVPG will meet a particular need.

Perhaps if Amdahl has reverse-engineered MVPG you could give us a
description of how it works?
