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. I should be set now until the end of my life at which point I shall consider owning this truly blessed machine one of the most cherished aspects of my life.Main Page | Shopping Cart | Purchase Information I have since bought numerous spares at apparently exorbitant prices, but the machine is worth it, and I do not have kids in daycare (so I can afford them :)). I was so saddened when HP discontinued the model (the end of a great era). I have used other machines, but this one is truly "the pinnacle of pocket calculator excellence" as another author once wrote. The complex number handling was a dream come true, and this hp great is very easy to program. It is equipped with anything a working electrical engineer (or any other engineer) needs. I bought my first as a senior in college after reading an add which stated that the hp 42S RPN scientific calculator was "engineered for the engineer." And I can say the it truly is. I continually marvel over this truly magnificient machine. This is the ULTIMATE ONE!!!!!Īn God said, "Let there be the hp 42S." The handling of complex numbers is top notch, and the unit is very easy to program with enough memory to tackle the toughest problems. This vintage (and still quite relevant unit) represents everything that made HP calculators the go to units for REAL Engineers and Scientists. No other manufacturer (TI, Casio, etc.) has produced anything close. This machine is a marvel and easily the best scientific calculator ever made. I would like to have a working unit all the days of my life. Verified purchase: Yes | Condition: Pre-ownedĪn God said, "Let there be the hp 42S." - CONTINUED.īought another one. Yet, they still won't do it! Read full review
We've told HP what we want and that we're willing to pay for it. Judging by the high prices HP calculators prior to 2001 fetch on eBay, I'd say many others feel the same about HP now. HP no longer deserves to be associated with quality. I don't expect HP to ever make a quality calculator again. I've asked HP's new President & CEO Dion Weisler to do just that, but I'm not holding my breath. Personally, I'd like to see an HP 15cii and an HP 42sii. In my opinion, the best scientific programmable calculators that HP ever made are the HP 67, HP 15c, HP 32sii and the HP 42s (although I'm very fond of the HP 29c and HP 34c) The best of the bunch I'd have to say is the HP 42s.
HP must have read them too and obviously doesn't care any more. If you'll read the reviews on eBay, Amazon and HP's own public reviews you' ll notice that Kinpo's calculators aren't as good as the one's HP used to make. Kinpo made the HP 33s and the current HP 35s calculators. Since then, Kinpo Electronics of China has been making scientific programmable calculators and HP has been putting their name on it. Many scientists and engineers use this calculator today, 25 years after its introduction."Īround the turn of the century, HP terminated its' calculator development team and decided to reduce the quality of its' calculators. "This calculator is often regarded as the best ever made in terms of quality, key stroke feel, ease of programming, and daily usability for engineers. The second to last Scientific Programmable RPN calculator HP made.
