We are in the final stages of preparing a cover for HP16c. The software will have to work on other "new" Voyager calculators. We have suitable firmware to do it. We are testing it, but I do not think we can run a fully-fledged testing process for it. We will have to work with it as is.
This is a printing sample of what we want to achieve:
It does not fall from the calculator, and can help you use your voyager calculator as a HP16c - the long-gone computer scientist calculator.
Will it work with the new HP15c Collector's Edition? If we can make it work with the latest HP12c, of course it can!
