The Gray Scale palette was just a passing thought, sorry to have
mentioned it. I have not done any investigation other than noting that
the EZ328 had that capability and was just musing on whether it could be
used to drive information to a color display. I guess that it depends
on which display that you choose, this may be what Palm did with their
color Palm III?
