Perfect calculator based on WP34S

[everett]

Hi All,

Only recently I have discovered the beauty of wp34s. I have been using HP 48G series for very long time and like them very much. I have also tried HP 35S. It is a nice calculator. But I was always been bothered by the fact that it has only 4 level stack. How do you guys keep track how many level of stacking are you using? Even though I like my WP34S very much, my handy work is not so good that I can't put all key prints nicely.

Anyway， I work in Dongguan city, close to Shenzhen. Most of the HP calculators are made by Kinpo electronics in Dongguan city. Since the
quality control in most current HP calculators are going down hill, I am
thinking to create high quality calculators with right keypads by designing
and ask Kinpo to manufactory for us. The circuit could be based on HP
30B with all goodies of WP35S such as crystal oscillators, USB, infrared etc. I hate the shape of the 20B and 30B, so the shape is something like HP 16S. Of course the calculator will be based on the firmware of WP34S. We might enhance both hardware (add more memory) or software capability (ask
wp34S team)

Do you think this proposal is doable?

Best regards,

Everett
