Interesting tech history! I wrote HP-41 software back in the early 80's, used in the field by surveyors in a natural gas pipeline project. When computer time was still expensive, programmable calculators did quite a bit of computation work in the engineering field. Your video is a nice reminder of the glory days of scientific calculators!
Nice collection! I've recently snagged a HP-41CX & a HP-15C. Awesome, awesome machines! This is my first real dealings with RPN, & I'm finally starting to get the hang of it.
@deadrabbit666666 The HP 35S is not a RPL-system calculator. It's kinda primitive, more like HP's old programmable calculators, before the RPL-families: HP 28, HP 48, HP 49/50. I could never go back to that. I almost exclusively use and depend on my own custom functions, which I access from custom menues. Only a masochist would deal with the old register type of memory management. And only a masochist would deal with algebraic calculators, Thus there is only the HP 50G today.
I own a few hp calculators over the years, one of which was a HP48sx, but due to could not provide a capable CAS. Decided to replace it with a ti 89, tried something different, but in the end ended up getting a HP 50g, mainly was accustomed to the old HP and RPN feature on the HP 50g is worth the money which I find much better for scientific/engineering applications, just didn't like the ti89 to much, felt a little lost and frustrated with the ti89, it doesn't seem as what I had expected.
I have an HP 35s, it's my first calculator from HP and in my opinion it's awesone! It costs more than other calculator but is more powerful. Doing exercise with RPN is faster than algebraic mode!
@nelipotfootfree Maybe that's exactly what they mean. Mine is in a cupboard ("on" key close to defective, occasional missing of keystrokes) and I started using my 41 CV and 48G again.
I presume you are asking about the slide rules. They are imprinted with logarithmic scales such that you can move the middle part to line up numbers of interest and see the result of multiplication, division, exponents, and values for sines, cosines, tangents. They are all we had to use before 1972, unless we used books of tables, except for simple multiplication and division.
@arenics it uses Reverse Polish Notation. something im learning to do now after talking to a physicist i know. he says "bite the bullet and learn the notation, math will come faster and you will make fewer mistakes. Algebraic calculators leave too much room for mistakes and do you a disservice to learning math. It will keep you focused on the order of operations and your equations will make more sense." So im looking at getting an HP.
The Albert Nestler A.G 23R IS THE BEST %#$*@ING slide rule for logs! It was good enough for Jack Parsons and Von Braun! Try the Voyage 200 and step into the real world if you really need a calculator!!!
The quality has really gone downhill on HP calcs in recent years. I'm sure some of them are faster strictly speaking, but you can have my HP 32SII when you prise is from my cold dead hands.
While this is really only nothing but spam, it is really interesting to watch. I just bought my first slide rule new in the box. A 1965 Pickett N3-ES 32 scale rule. I have an HP34c and love it. Mabey they should reissue the 34c and other favorites. They did it with video games! They should even keep the red led design. Now THAT is something I would buy!
Hi, thanks for making the video, and for your contribution to rocket science. I also have the 33s and besides the weird chevron layout I think it's a great little device.
good job. There is a HP customer-video contest because of the HP-35 anniverary. If you send your video in you might win something? BTW, after summer HP will launch a new RPN calculator (HP-35s)
Waiting for my new HP 50g to arrive ^^

I am a proud owner of a slide rule and an HP 35s. I also have a Texas Instruments TI-83 Plus.

I have heard the 35s looks like the early pioneer calculators but does not function as well. I have a 50g and a 42s myself and am content with them.

Those of you who say that HP's quality has gone downhill in recent years, try the new HP 35s.

it works on the principle of logarithm for computation, remember that logarithm turns multpilcation into addition,

how this "calculator rule" does works ? how is it used ? I'm engineering student and I never see one of that before...

Good stuff Gerry, I also use a HP 33s, they are excellent for most fields of surveying, particularly geodesy.
