Erik Fair observes:

   .......One minor note on the NS [16032] MMU, is that apparently it has
   512 byte pages ingrained into its structure, and so those of you who
   want larger page sizes than that are in for an interesting time....

It's quite true that the MMU has 512-byte pages ingrained into it.  So?
The VAX does too.  If you want bigger pages, you simply do everything N
512-byte pages at a time instead of one 512-byte page at a time.  As an
example, National's 4.xBSD port does everything 2 pages at a time to
give the effect of 1024-byte pages.  Almost any paging hardware has to
make a firm decision about page size and stick to it.
