The Motif on the Zoomer is standard. The parameters for using motif on the
Zoomer provide the "limited" motif functions that you speak of.
I am currently using the Desktop Motif.geo on my Zoomer without any problems.
Also, the Zoomer supports all the motif switches documented in the Geoinfo
(Just like the desktop).
Well, I think Casio/Geoworks limited the functions in order to make it easier
for a new computer user to use it.
