43s status

It was nice if we could have a draft of the project specification.
Surely the authors must have one by now.

The 43S source forge repository was updated on 2014-04-30.
The project description mention USB, SD, an I/O capability to interact to a host computer:

This project is to develop firmware for a pocket calculator that is a super-set of the legendary HP-42S RPN Scientific. We strive to create a serious scientific instrument again like we did with the WP 34S (look here: https://sourceforge.net/projects/wp34s/).

WP 43S is going to grow on our own hardware now. It features a state-of-the-art display, a USB port, an SD port, and eight rows of keys - one of them for softkeys.

WP 43S is going to come pretty close to the ultimate RPN scientific calculator - at least that's what we will be trying to reach. That means it will be instant-on, including all the mathematics you can expect in such a package, all the keystroke programming capabilities you need to solve repetitive as well as iterative problems easily, and all the I/O channels for reliable backup and easy linking to an arbitrary host computer.

Right now, the prototype hardware is under development still - and the firmware team is waiting for it to start its work asap.
