Summary: Atari ST does have basic address translation.

In user mode the GLUE chip adds an offset to all adresses. It's not
the best memory management hardware ever, but it's enough to make
MINIX possible.

Even if it didn't have it, though, you could still do it. Just teach the
compiler to generate register-indirect branches and data access. It
works for OS/9.
