With this in mind, HP built the HP 9100 desktop scientific calculator. The corporation recognized two opportunities: it might be possible to automate the instrumentation that HP was producing, and HP's customer base were likely to buy a product that could replace the slide rules and adding machines that were being used for computation. In fact, I am about to sell my HP49G because the 35 makes its important functions more accessible while the 49's more powerful functions are better done on a computer.įor the record, I also own an HP17Bii financial, having the same form factor as the H32 and also a real favourite.In the 1960s, Hewlett-Packard was becoming a diversified electronics company with product lines in electronic test equipment, scientific instrumentation, and medical electronics, and was just beginning its entry into computers. However, if you need more power then the 35 is superior, no doubt about it.
I recommend the 32 as a great calculator, enormously reliable, fits in your shirt pocket more neatly than the 35 or later models and is functionally capable. The HP32 is a shade narrower, thinner, shorter and thus neater to hold, nicer to press, and has most of the functions of the 35. The HP35 is functionally superior and is cheaper. The 35S is really nice but today I found the HP32Sii in an obscure place. Over ten years on I lost the next one two weeks ago and bought an HP35S to replace it.
Lost it on a plane in the 90s and went out to buy another as soon as I realised the loss could not be recovered. Notice that I do not own a 32s or sii.įirst the history: I purchased an HP32 back in 1988, after owning HP25 and HP29C. I own a 12C, a 15C, a 28S, 41CV, 33S (another failure), a 42S, 28s, 48SX, 48GX, a 49G (a backward step, more like backward run with hurdles, for HP), 49G+ (better than the 49G, but still behid the workmanship of 48GX), 35s and a 50G (Someone in HP decided to do somthing good after so many years of failures after the 48GX). I may pay more than $150 for a HP 42s or a 41CX than have way more use than the 33sii. Even the 1980s RPN (again on purpose due to those damn NCEE Nazis) look and operation. I know there are a lot of HP 32s and 33sii lovers out there, but if you need another go and get the 35s. The 33s did not have enough memory back then or today. The HP 35s has a lot of limitations (on purpouse so NCEE approved it) but at least it has more memory than you can really use. If you are looking to buy one for the EIT or PE, you just go ahead and get the HP 35s for $55 to $70. May be for a collector, but for a person that is going to be using it, it is just a plain waste of money. I find it ridicuolous to pay more than $50 in 2010 to own this. If you were going to go for an RPN calculator, you did whatever you need to do to get the HP 28C or HP 28S. Back in 1988 when I was an engineering student, this was not the norm. This was a nice calculator for highschool and highschool math competitions.
