Consumer Evaluations
I am a diehard RPN and HP calculator fan. I purchased this calculator for the PE exam. HP calculators I've owned include HP41c, HP42s, HP12c, HP17BII, HP19BII, and HP33s. The HP35s is generally an HP33s with most the ergonomic style flaws and excellent issues of the HP33s fixed, along with a few added enhancements. It really is what the HP33s must have been in the initially location. But, along the way, it also introduces a few design flaws of its own.
Obvious pluses: The keys on the HP35s feel just about like the ultra high superior keys on the HP41c, not completely there because the ones on the HP35s are flatter and have less travel distance, but really close. But, not like those on the HP41c, some of the secondary colors on the keys are only painted on. How extended would the paints last? It comes with a super good semi-rigid vinyl case. The LCD display is fragile, but it seems to be dust-proof and has excellent contrast. The built-in metric/imperial conversions and constants library are also good. 1 significant enhancement more than the HP33s is the capacity for a plan to refer to a line number rather of a label name through conditional branching. This feature permits the writing of applications that do not use up a lot of the valuable program labels. The equation solver is fairly highly effective. It comes with built-in equations for solving 2x2 or 3x3 simultaneous equations.
Obvious minuses:
1 key annoyance to me is that the HP35s does not have scrolling comma separators as I enter a extended number. So, if I enter 12000000, I have to hit the ENTER button to see it displayed as 12,000,000. The lack of true-time, scrolling 1,000 separators makes it quite straightforward to make information entry errors. The HP41c, HP42s, or even the lowly HP33s have scrolling commas.
There are only 26 single alphabet plan labels and only 26 variables, severely limiting the number of applications one particular can store, taking into consideration the somewhat massive 30kB memory accessible(the HP42s only has 8kB). The manual has a fine number of beneficial programs, but in reality one can shop only a few of these programs on the calculator at a time due to the 26 program label limit. I can shop even more programs on the HP42s even although it only has 8kB of memory. In actual use, most of the 30kB on the HP35s will go untapped.
It is a shame HP chose not to involve multi-letter alpha-numeric capability as they did on the HP41c and HP42s. Rather of labeling a program that calculates the time value of funds employing a single letter such as "T", I'd considerably rather be calling the system "TVM" or "Income" or some thing straightforward to recall. The very same a single-letter restriction applies also to variable names. The listed battery life is on the brief side. Two hours of use per day will final the batteries only about 9 months.
Whereas the HP42s gives four kinds of curve-fitting and has capability to choose 1 with the perfect fit, the HP35s delivers only linear regression. Also, not like the HP42s, the HP35s doesn't have any built-in matrix capability to evaluate determinants, inverses, although it does have built-in 2x2 or 3x3 simultaneous equation solving potential as mentioned earlier. You can plan all these missing capabilities in but you will use up countless of the precious 26 plan labels in a hurry.
The STO important which I use very commonly is now subordinated, requiring a shift important, whereas the "Mode" crucial which I seldom use is main.
The display has substantially extra glare than other HP models I've owned.
Though I will pretty much by no means use the algebraic mode except when writing equations, I must mention that its implementation on the HP35s is clumsy. On other algebraic calculators I grew up with, the number precedes a function essential (such as COS, 1/x, log) and the function is executed as soon as the function important is pressed. In other words, even although they are algebraic calculators, their function keys function in postfix or RPN mode.
The essential sequence is
45
COS
The worth of .707 is displayed as soon as the COS key is pressed. It is extremely straightforward and intuitive. This is also how the functions work on the HP33s. But, surprise, this ain't how it works on the HP35s!
On the HP35s, you have to start by 1st pressing the function crucial and then punch in the number and then press the Enter important to get the worth.
The crucial sequence is
COS
45
ENTER
The ENTER essential functions as the equal sign important in algebraic mode on the HP35s. Hitting the ENTER crucial now becomes mandatory to get an answer from just about any operation. Although this peculiar algebraic method might possibly make sense when writing equations, it is highly cumbersome when carrying out calculations on the fly, primarily for an individual employed to the keystroke effectiveness of RPN.
I occasionally scratch my head trying to figure out why for the final ten-15 years HP kept churning out mediocre calculators, with each and every new one worse than the previous 1. Why mess with winning styles and dumb them down to the level of TIs and Casios? Yes, the money is exactly where the masses are and the masses are the high school and college crowd and they use predominantly TIs and Casios. Then it dawned on me that the sales execs, designers, programmers, engineers also have to somehow justify their existence by rolling out new models and discontinuing older but superior models. The HP35s appears to be a step to halt the march toward mediocrity. Does it succeed? Yes, largely. Even though the construct top quality is great, it certainly could have been created better.
Even although the STO important is now subordinated, the HP35s fills the need to have for simple everyday quantity crunching due to its ergonomic form factor and ease of use combined with a reasonably rich set of functions. The HP50g fills the will need for heavyduty scientific/engineering use but is too clumsy for everyday standard number crunching.
I'm confident as I use this calculator a lot more, I will see significantly more of each the pluses and minuses. And, if I were to rate this calculator in comparison with any Casio or any TI, I would give it ten stars if I could. But I rate it in relation to what I anticipate an HP calculator really should be and so I rate it four stars. If the HP35s came with alot more system labels and variables than just 26 of every (A to Z), multi-letter alpha-numeric information entry capability, matrix capability up to [5x5], four kinds of curve fits and greatest of fit, main STO and RCL keys, I would rate it 5 stars.
The 35s is the most interesting calculator HP's made in a when. When I am positive their intended market place is the legions of dedicated HP users, even if you're not a lover of antiques you should certainly give it a appear.
A definite improvement on the 32sII, and in common I would advise it more than acquiring an overly-high priced made use of HP. Whereas the hardware is not really as nice the 35s will need to have a a lot longer battery life, and has alot more than adequate memory to hold any reasonable quantity of applications.
It is physically larger than a 32s and it is not honestly "pocket-size". However it really is not that major compared to modern day scientifics and the larger display is worth it.
It feels extremely solid, except for a battery door which pops off a bit too quickly. Lithium coin batteries are so much a lot easier to deal with than watch batteries that I'll happily accept the tradeoff.
The keyboard is slightly soft compared to older HPs but that is been effortless to get put to use to. It has a definite click, superior-sized keys with a substantial Enter key, and should really appear really familiar to HP users. However it uses painted-on important symbols which I suspect will show wear rather easily.
Crisp display, simply readable from practically any angle. A large improvement over the LCDs in HP's older models.
It has RPN and algebraic modes, as properly as an EQN important which enables algebraic entry while in RPN mode. Most keyboard functions have an EQN/ALG counterpart, and even though algebraic formulas can be utilized in programs you'll still have to have to use RPN for conditionals and loops.
The excellent mixed-base number support is a pleasant surprise. In algebraic mode you can quickly enter a calculation in mixed bases with out altering the current base. (This mainly functions in RPN, but there is no way to enter hex A-F with out switching modes.)
Programming is similar to the 32s and significantly of the manual is identical--the only main alter is additional memory. The 35s' overloaded keys and straightforward design make programming a lot less complicated than an RPL-based calculator like the 49g+.
Why did it only get four stars? Two troubles:
No I/O. Being able to backup memory would make me a little happier and I've come to expect this from a contemporary programmable.
And, RPN applications typically run only about as quick as on the 32s, generating its programmability less beneficial than otherwise. Following 15 years I expected to see at least a aspect of five speed increase.
In short: I like it, and I consider you will too. In terms of price tag and ease of use it can not compete with, say, the Sharp EL series. (The new HP 10s is a actual contender there.) But the HP 35s' programming capabilities set it apart from any of the affordable scientifics. If you will take the time to master RPN, you will discover writing programs is less complicated and much more handy than writing the similar thing in a Simple-like programming language.
