Well, Andy, the page size on your beloved Vax is 1024.
I beg to differ. On pages 16 and 17 of the VAX Architecture Handbook, it
states:
``Virtual address space is diveded into @b(pages), where a page
represents 512 bytes of contiguously addressed memory. The first
page begins at byte 0 and continues to byte 511. The next page
begins at byte 512 and continues to byte 1023, and so forth.''
.....on page 9 of the same book, it defines a byte as 8 bits. Sorry, Goldfarb.
You're probably confused because Bill Joy et al decided to use 1k file
system blocks (so of course, Berkeley unix swaps at this size, but the
VAX hardware itself thinks in 512byte pages.).
VAX manuals in hand,
