Product Information. The Hewlett Packard 35 calculator has a solution for everything, be it everyday arithmetic or statistical analysis. The large 2-line display of this HP business calculator features an adjustable contrast that enhances legibility. The 42 built-in physical constants with unit conversions, inverse functions, cube root etc. Makes this HP scientific calculator a must have engineers, surveyors, college students, scientists. The Hewlett Packard 35 calculator offers memory space of 30KB along with 800+ independent storage registers. Several features like inverse functions, cube root, logarithms, exponents, factorials etc., in this HP business calculator make your life all the more easy.

This HP scientific calculator can be used for many of your exams like- SAT Reasoning Test, SAT Subject Tests in Mathematics Level 1 and Level 2, ACT Mathematics Test, PSAT/NMSQT, AP Chemistry/Physics etc. Iconic collectableHP quality sure shows up in this dated calculator.

It looks and works almost as well today as it did in the 1970's. Things to watch out for: 1. The nicad batteries leak and corrosion can be a problem to the battery contacts.

The ON/OFF switch has too much grease when applied at the factory. To take it apart, you must remove 6 case screws and 8 inner screws, then wipe off the grease. Two of the case screws are under the label. Two more are under the lower feet.

Don't remove the lower feet, just bend them back to get to the screws. Is this a good value? Not really considering its high collector cost and comparatively few math functions. Still it is a must-have for a collector. I find even the replacement battery packs don't hold a charge for long. Nothing really to do with the caluculator, it's the nicad technology of the time.Verified purchase: Yes.

Takes me back to the 70'sAs a student ready to enter college in 1976, I saw an article for the HP-35 and got a summer job to save my money to buy one. I had one of the earliest units sold by HP, picking it up directly from HP headquarters. At $395 in 1976, it was DAMN EXPENSIVE, but made my life as an engineer at UC Berkeley so much easier. While I could use a slide rule, this made it unnecessary, and it was so cutting edge a the time. (Remember that 4 function calculators cost $125 or so.)I sold my HP-35 a long time ago, but always wish I had kept it.

So when I saw one for sale, I had to put it back on my desk. This was the first calculator to do trig functions that you could hold in your hand.Owning one again just makes me smile, and frankly, I enjoy using it again.Verified purchase: Yes. An ingenious solutionLet's face it, the HP35, 45, et.

Al., pocket calculators, revolutionary when first introduced in 1972, have long since outlived their indispensability. Still, those of us who bought one at the time like to get them out every once in a while.If you're like me, your original battery has leaked and you've lost your plug-in charger. I had a calculator I couldn't use. I found a vendor selling batteries (and bought one), but when the batteries run down, what do I do?That's when I stumbled on this USB charger assembly. Truly an ingenious and simple solution. Whoever designed it has married a standard USB 1.0 A connector to the special-purpose battery connector for the HPxx calculators.

It uses the power connections (and only the power connections; the computer does not recognize the cal culator as an attached device) to provide power to the HPxx (and to charge its battery, if you have one).My only reservation is the voltage. Standard USB power specs center around a nominal 5.0VDC.

The calculator is specified at 3.75 volts. I don't know if the calculator can withstand 5.0VDC at all/for an extended period/???

Nor can I find any documentation about supply voltage tolerances for the HP-45. There is no documentation with the cable to indicate what (if any) limitations this places on its use.

Since there is no documentation, it also can't be determined if the developer put some sort of dropping resistance in the path to get the target voltage to 3.75. This would be unlikely, as it would not only waste USB power in the form of heat, but it would require knowledge of the specific load of each HP calculator.Verified purchase: Yes. Ended the rule of the slide rule.Few people today even know what a slide rule is. And of those that do, few remember how to use one!

HP-35 was wildly expensive for it's time $395 in 1972 (or about $2,200 today) this machine easily paid for itself in productivity and ushered in a era of even more powerful computing for everyone. This marked the beginning of the end for slide rules. My Dad brought home a loaner in the grey case when he was working on the Apollo mission at Grumman. I was hooked forever!Verified purchase: Yes.
