680x0 assembler development environment needed

[Margaret M Reek]

We are looking for a 680x0 assembly language program development
environment, suitable for use by students.  In particular we are looking
for an assembler that produces listings, follows the Motorola syntax, and
has some minimal macro capability (this last is the lowest priority item
on the list, the others are absolutes).  We then need some reasonable
debugging environment under which to run the programs.  We are running on
Sun 3s, and the Unix assembler is pitiful and adb is hardly something we
want freshman to have to deal with.  

Any leads on either a commercial product or public domain software would
be appreciated.  Also, if you know of a good textbook using the 68K would
be helpful.

Please reply by e-mail, as I don't normally read these groups.  I will
post a summary of responses, so if others are interested they can get the
info in a concise way.
