I have very few units of HP30b left - anyone interested in the wp34s needs to act quickly - or we will exhaust our stocks.
I are finding increasing problems in sourcing HP30b. Despite being a good calculator, its external aspect never won a lot of friends and it is not part of the EAME HP calculator offer anymore. In fact, I can’t find it except in very strange language combinations - which is not relevant for wp34s conversions.
If you are not aware of what a wp34s is, please read here for a description. It is by far the most complete scientific, non-graphical calculator ever designed. Taking profit of the software development kit (SDK for short) made available by HP, Bonin, Dale and Von Cube, helped by the testing and feature suggestions of the best and more experienced HP calculator users, created the most advanced and fastest calculator ever. All imaginable constants - you have them. All imaginable probability distribution functions - are there. The most obscure mathematical functions - there too. Do you feel limited by a 4-level stack? Get 8 instead. Are you accustomed to use the 4th level replication feature, and you want to keep it? you can set it of 4-level stack too.
Eric Rochlin created overlays of very good quality, that, once applied to the calculator, create a professional product that you can take with you to work.
There is also a fully fledged, free version for smartphone - at least I have it on my iPhone and iPad. I think that it is an excellent way of getting in touch with it. You can search in the respective app shops for wp34s and you will find it. Install it!
You can download the manual from our website page too.
