The now-defunct Culler machine was originally going to "just do the
wrong thing" on unaligned accesses.  Fairly late in design, logic
was added to trap on unaligned accesses.  As I recall, one of the
arguments for adding that logic was that it was difficult
(impossible?) to achieve F77 validation on a machine which "just
did the wrong thing".  Can anyone comment on this?  Does the F77
validation suite actually force oddly aligned access and expect
them to work?  Is there a qualified F77 for the RT PC?
