- Hmm. The way I remember it (from Kane/Hawkins/Leventhal and
- the Motorola books themselves), the modes are address register
- indirect with displacement, and address register indirect with
- index and displacement. The displacement is always there, at
- least on the 68000 (things change on the '020). Could you

- in case.
