Is this normal? ODT Question

So I've got a Q-bus system with 64KW (128KB) of RAM that is allegedly an 18
bit backplane. When I'm in ODT I can type:

_at_177770/
And enter values for 1777772, 1777774, 1777776, and then it wraps around to
000000.

If I start at 200000 it works until 3777777 and then wraps to 2000000. So
it seems to not cross a 64KB boundary. Also the boot area is 177300 ? so it
is in the upper 4K of the 64KB address space, is it legal to have memory
"above" the I/O page?
