Or MMU. Without that, you're in for one hell of a ride; NetBSD doesn't work
on machines without a MMU at the moment.

512K is very tight for runtime; I don't think you'll fit a *usable* NetBSD
into that, even after tackling the MMU issue. (You might be able to make it
print stuff to the screen, but forget a shell prompt. 8-) If "memory" here
is something like flash storage, and there's more *RAM* memory, this might
be more feasible.
I don't mean to discourage you, of course, but there are classes of hardware
that are best suited to particular OS's. For a machine as you describe,
there are other "embedded" OS's (designed for the smaller footprint, which
don't necessarily scale well to larger hardware) that would be more
