Here it is on a DEC 3000/500 (Flamingo) running OpenVMS 1.0 (field test)
    "Of the physical pages in use, 934 pages are permanently allocated to VMS."

However, this is misleading since the OpenVMS is using "pagelets" and variable size pages.
The SYSGEN parameter PAGE_SIZE on our machine is 8192. I believe the pagelets are 512
byte blocks.  This usage on your system will depend on SYSGEN parameters, e.g. how
much  GBL pages/sections you set up.
