Pack to create a WP34s, composed of an adhesive overlay and a HP30b, flashed with the latest stable version of the software created by Paul Dale and Walter Bonin. There is a 10 € contribution to the project for each calculator sold.
We cannot guarantee the freedom of the software from bugs of any kind. However, we will re-flash it free of charge as many times as needed - shipping back and forth to be borne by the customer.
We are shipping now the version 3.2 with new overlays
We do not have additional flashing cables to sell
There is an interesting WIKI devoted to the WP 34s project
And here's a link to the manual:
