|Comment||This calculator was designed to compete with the
HP-45. And when looking at
the feature set
it indeed matches the HP-45. But different from the HP-45 it comes in
absolutely cheap plastic housing. The keys do not nearly have as good
a "feeling" and the silver key labels don't look very durable
Certainly not a competition HP had to fear. Nevertheless, it is one of the very few non-HP calculators that uses RPN entry mode!
