How's WP-43S Project Going?

[jwm]

What I would like to see is an open hardware standard, nice, calculator case and board with blank keycaps that can be flashed by different communities with different firmware. RPN, RPL, old school casio, dedicated beer pong score keeper. Pre-die-cut label sheets that can be fed through a standard inkjet/laser printer could also be made in bulk.

The HP 30B is the closest thing to this now and I have been playing with writing alternate firmwares. Right now I have one based on the joy language (http://en.wikipedia.org/wiki/Joy_(programming_language) ) and the lambda calculus. The screen is a real limitation though. 2 lines dot matrix a la 42s,35s is my sweet spot.

I would love to be able to reprogram something like the HP 35s form factor from complete scratch with no HP firmware and pure open source, but it's too expensive to repurpose for a lot of people. it has a nice shape and physical design but the firmware oversights just grate on me, I'm gonna return mine.
