How's WP-43S Project Going?

[Waon Shinyoe]

I noticed there is some discussion in the old forum about a prototype WP-43S. I'm curious about the details of the great device. And I'm very willing to find OEM factories in China to put it into mass production! And Made in China will be surely cheaper.

And there is another DIY calculator project called ArithMax 233, mainly designed & coded by Zweb, a member of cnCalc.org. A prototype is already made, and now we are discussing about further modification, improvements and mass production. Therefore we are considering about building the whole cover and keyboard all by ourselves, since my father own a plastic factory.

So I have another plan, called Project Renaissance, to rebuild the 48s-style keyboard based on 1991-06 HP Journal and the patent documents. (No double injection though)
