While UNIX supports virtual memory, the 11/70 does not.  That 64K is all
you get on an 11/70.  In fact, VAX stands for something like Virtual Addressing
eXtension or some such.  I liked the 11/70 I used to be sysop for (under unix
2.9, mind you, not that *other* DEC OS) but it really only served as a machine
for undergraduate homework and small projects.  64K really isn't much...
