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?
