I have written instructions explaining how to make your own WP34S, but if you would like the work done for you, this package provides you with a full WP 34S calculator, with the following components: Later, Marcus von Cube joined the team and made it run on the HP 20b/30b platform.Īt this point, the WP 34S functionality is comparable to that of the long-discontinued HP 42S, but expanded significantly. The software of the 34S was written largely by Walter Bonin and Paul Dale, initially just as a PC program. It is not an HP product, but it is rather a community-created product based on an existing HP calculator platform. The WP 34S is the most powerful scientific (non-graphing) calculator on the market.

Note: I am a bit behind on making these, so please expect a delay of 4-6 weeks before shipment. Main Page | Shopping Cart | Purchase Information
