Comparison of HP 32SII, HP 33S and HP 35S scientific calculators

A comparison of three HP scientific calculators with similar functionality but very different different physical designs. In video I talk through the differences in design and functionality, and talk about the pros and cons of each device and the history of their development.

I love my 32SII. When it stopped working I bought a 35S. It's a pretty good calculator but there are a couple of things that I don't like about it. The location of the execute key is not as well placed ergonomically as it is on the 32SII. And to execute a routine on the 35S, the ENTER key has to be pressed in the sequence, which adds an extra stroke. The 32SII only requires the XEQ key followed by the assigned key to run the routine. No Enter key required. I used the 35S for a few years and the Enter key crapped out so I bought another. But then I went on ebay and bought a 32SII and keep the 35S in the drawer as a backup. I miss my 41CV but I like the 32SII more.

Looking at the 33S makes my brain recoil. Such an unfortunate era of industrial design.

like them all my daily calculator is 49G+ I have 32SII and 33S and 35S, used 32Sii for years but got damaged in accident love RPM bring it back

The number of feet on the 32sii actually depends on when (and where) in the production cycle your particular unit was made.
USA and Singapore models have four feet. The later Indonesian models only have the two feet....and are reportedly less reliable.
(Nice videos....thanks for doing these.) :)

I love my HP-32SII. I bought it 35 years ago (1987) and it’s pristine. And the battery lasts forever. Incredible quality.
My HP-35… left-Shift and Enter became erratic after a couple of months.

La 32s es mucho más bella que la 32sII, sin embargo la 32sII tiene mucho más funciones y tiene otra variante en color con teclado verde y púrpura que la hacen también muy linda. Todas estas son programables y te van a encantar si deseas adquirir una de estas con el método RPN. Excelente video.

My HP 32SII is a little cutie. I also have a beautiful, immaculate 48GX, with all the physical programming books. When the 33S came out ugh....
Is it true that RPN suffered when HP calculators became dual-mode?

At 8:48 I am completely baffled about what you are showing. The sin of 2.75 is about 1/12? No, that is just absurdly wrong. Yet I don't see how you got the calculator to act so weird.

As long as it tells me what 2+2 is, I'm happy.

My 32SII has 4 feet at the bottom. It was made in the US. Never changed the batteries in it. Still working.

I own several hp 33s and hp35s. In my opinion the most annoying thing is the durability of the keys. Many of my calculators, in particularly the hp33s after a few months have the keys not reactive and I have to push them two or three times to get the digit. I don't know what to do about that.

Can you please tell me if in the HP33 (in ALG Mode) you can scroll through your calculation history with the UP arrow on the Home screen?
/THANKS in advance!

Your opinion really helps, However you're speaking is very hard to understand, not enough voice variation or volume and to get around that I have to turn on closed captions. I did learn a few Tidbits, which I am grateful for.

Really nice concept and content. I could not enjoy the video because you mumbled throughout. Sorry if I'm being to critical. I'm sure you can operate the calculators better than I.
