thanks for sharing this awesome collection

[@commtechengineer612]

These are beautiful! I tried showing off my calculator collection on a first date......There was no second date.

[@peterhaagen8506]

Wow what a nice collection. I couldn’t have finished my study without my 41C and card reader. I still use it. And I don’t like to use something else when I need a calculator. I didn’t know that hp made so many different calculators. ❤😉👍

[@jurjenbos228]

The HP15C is arguably the most advanced calculator ever my by HP (if you don't count the HP35). That one was way ahead of its time, although not many people realized how advanced it was. I remember the eyes of my professor when I had finished the problem that I was supposed to solve on the university mainframe computer on my calculator!

[@michatroschka]

hahah thats a nice story, i got a 15C from my mum for school, my fellow classmates made fun at me for it being RPN . would love to get to know it more.

[@johnquant9924]

My dad did everything on his 15c, and I considered myself highly favored when he let me take it to school for my Algebra class. I later got a 48G, which can do everything, but it doesn't have the crisp display, the quality buttons, convenient size, or sheer class of the 15c.

[@EJEuth]

@@michatroschkaFor them, a good saying: “Ignorance is bliss”

[@w9gb]

Still have my 15C from graduate college. Although most MBA students used the 12C, my STEM undergrad background preferred 15C. I was tempted to get 16C, due to my comp. sci. classes, but gladl I picked up 15C. 5+ years ago got the SwissMicro 42S

[@MrWaalkman]

When I took Electronics at Pikes Peak Community College (Home of the fighting Aardvarks I'll have you know) in the '80s, I had to buy a HP-15C calculator since my TI-35 wasn't allowed. Not only that, I also had to take a class to learn how to use it. I immediately fell in love with it, and the 15 is still my go-to calculator.

[@adrianodistefano3470]

Thank you Erix for this wonderful presentation!! A time of true inspiration in design and quality that defined HP at the time! I own 2 of the HP19 II Business Consultants 😀, a HP 12CP and waiting for my new HP 15C... Now after all these years I have the opportunity to learn RPN which is a breath of fresh air!!1😀😀

[@herminiozepeda3190]

Incredible collection you have. Congrats !!

[@ErixCollectables]

Thanks!

[@ast453000]

beautiful collection. I'm very jealous. I love the voyager series especially. I can't understand why I like old hp calculators. that was a golden time.

[@ErixCollectables]

Thanks for the compliment. HP calculators were very nice indeed!

[@radio655]

What a beautiful collection. The 41C was available in my school time but priced far beyond my reach.

[@4thesakeofitname]

Wow, I'm amazed by the adorable and miraculous HP 41CVX which has so many extension and connectivity options with programmability, and comes with a cool LCD display, and highest quality body-keyboard build, and still at pocket size. It must have felt like a portable magical workstation for engineers and scientists who should do computations on the go, or who wouldn't afford a mini-frame or personal computer just for technical calculations. It feels like the extension programs and functions included a great many practical cases, making the calculator stand still under the test of time...

[@user-ew6el9wm3s]

Thank you for the HP history on that system. I am going to buy the hp-12c.

[@rapscallion3506]

Great assortment, Eric. I appreciated all the history as an HP 41cx enthusiast myself… and 100lx… and 12c.

[@herminiozepeda3190]

I loved my HP 41CX.

[@peterdegelaen]

I still have the HP20S; I bought it in the late eighties. I worked as an IT systems engineer and it also has the binary, hexadecimal and octal functions. The calculator still works and I still use it today.

[@jmfa57]

Thanks for yet another great video on your HP calculator collection. While I still use my HP-45 and HP-67, as well as my HP-42S, my HP-32SII languishes in my briefcase, seldom used at this stage of my working life. My favorite calculator of all time was my HP-25, which I bought, then lost, during my college years in the late 1970s. I finally got another one just last week from eBay, and man, did I ever miss using that one! Thanks again!

[@flat4-]

Nice collection and good story telling. I still remember in the late eighties in school when some classmate brought an HP15c, even our teachers were amazed by the design and functions it had....

[@bngr_bngr]

I still use a HP12c all the time. I have three, one I bought new, another I found thrown away at work. It needed new batteries. Another I found on the street run over by traffic. After cleaning it off, it still works perfectly. Just a little scratched.

[@ErixCollectables]

Awesome story. I never find HP calculators in the street. I guess I have to look more carefully from now on!

[@joseph_donovan]

The HP-16C can't be had for love nor money these days! An adorable calculator! Powerful too.

[@apersson850]

I still have mine.

[@MrNamdang2011]

I bought my first HP 25 back in 1976 in my first year of college. Later I bought HP 27C, HP 41CV, HP41CX, HP48. Currently using HP32S, HP50G.

[@m.a7473]

What a collection! Coming from Japan to USA, my first HP calculator purchase was HP-28c. I always wanted to buy YHP (Yokogawa-Hewlett-Packard) calculators but never able to afford the one while worked in Japan. I used the 28C for about a year then upgraded to 28S, and kept using it until the electrical connection at the folding hinge went bad. I replaced it with 48G and I still use it time to time. Your video invoked a good memory of the time period when I was constantly amused by browsing through Educalc catalogues. Thanks for the video.

[@ErixCollectables]

Thanks for the message. Seems like you had quite some good calculators. Never seen a 28S develop that hinge problem. Back in the day I met with the owner of EduCALC and we exchanged some business ideas.

[@geraividet]

Looks like SwissMicros has taken over the production of rpn calculators

[@petermikus2363]

Yeah kinda a shame ho deasnt make rpn focused calculators anynorr

[@WiltonSilveira]

Eu queria que a SwissMicros criasse uma evolução da HP 50g, com a nova versão da linguagem RPL.

[@lowellmccormick6991]

That is a fantastic collection Erix. HP turned me into a calculator snob. I refuse to use a calculator with an equal sign. I got a used HP25 in 1978 then progressed thru HP67, HP41CV, HP32SII and now currently on another old HP32SII I picked up on ebay a few years ago. I'm not going to count the 2 HP35S I've used because I didn't like that model. The first one lasted a couple of years and the Enter key stopped working properly and after getting another and hating that I needed to press an extra key to run a routine, I put it in the drawer and got my current HP32SII from ebay.

[@jaro-ch]

I've sold in 1982 my cv to switch to the cx. The cx was a great tool and I wrote a lot of programs during my education to became a mechanical engineer.

[@skfalpink123]

Many thanks for that excellent video! As a software engineer, I still use my HP32SII on a daily basis - primarily as it supports single-button conversion of number bases. Although the 48G series also supports this functionality, the extra button press (R->B) is one button press too many. Incidentally, I actually have two 32SIIs, just in case one ever decides to die. So far, so good!

[@juancarlossanchezveana1812]

Amazing

[@thomasmaughan4798]

1:05 HP-41C was my favorite calculator. I had the bar code reader wand with it. I made a compiler for it so I could print barcodes for programs I created. I still use HP-11C and HP-48GX. I started my collection with HP-35 and the most sophisticated was HP-70 but I never did use that one much. It sits on my desk because it is pretty.

[@stefanogrossi6420]

Amazing video. I still own a 12c, 12c platinum, 42s, 28c and 2 model of the amazing 28S

[@sojourningyid1655]

I loved every second of your Hp show-and-tell...new sub 😊

[@ErixCollectables]

Thanks for watching and subscribing. I’m building a Collectables shop now which will have loads of calculators and other vintage tech!

[@WiltonSilveira]

Coleção incrível! Tenho uma inveja saudável de coleções assim! Se algum dia eu ficar rico, farei uma coleção com HPs, Texas e Casio! Faltou citar a venerável HP 50 g, que lastimavelmente foi a última da série com programação em RPL (combinação de RPN com Lisp), tida como superior à HP Prime. Na minha HP 50g (adquirida em 2015, se não me engano, e o último ano de produção dela) só veio de impresso o guia de apresentação. Os demais tive que baixar os PDFs. Sinal dos tempos... Se não me engano, tinha uma importante equipe australiana trabalhando na série 48, 49, 50, em cima do RPL.

[@ErixCollectables]

Thank you for watching and subscribing. Happy collecting! You wrote you were missing the HP-50g but it was introduced in 2006, much after the 1990's.

[@famgzzgtz]

Great collection!!

[@ErixCollectables]

Thanks!

[@EJEuth]

Great collection, Erik 👏👏👏👏. Nice to see your chronology overview too.

[@ErixCollectables]

Thanks for watching!

[@mellowtube]

i owned the 28c and 48sx and 41cx now I own the hp prime g2, an absolutely fantastic calculator.

[@petermikus2363]

So if anybody is interrsted in the hp viyager series and rhe hp 42s or the hp41cx id recomend checking out a company names swiss micros they make remakes of those calculators Ill list them here for you the numbers correspond to the numbers ob the hp calcs Dm11 Dm12 Dm15 Dm16 Dm42 has a bigger screen and a aditional row of keys for the menu Dm41x a hp42cx in the format of A hp42 Also all of these calculators are mkre powerfull processor wise then the hp's How ever the keys arent as good but they are probably the best ones after hp when it comes to keys the dm42 is regarded as the worlds most precise pocket calculator it goes up to e5 digits how ever thats kinda overkill all are nice calculators made from metal and plastic

[@thomasmaughan4798]

Thank you. I have never heard of (or I don't remember) Swiss Micro calculators.

[@sundancer667]

4:20: The "X" in 41CX does not stand for 10x the memory (it actually does have the same memory as the 41CV). The "X" stands for "extended" because it had the XFunctions (even more functions than in the XFunctions-modul) + XMemory + Time_Module (hardware + software) build in.

[@ErixCollectables]

Ah thanks. I stand corrected!

[@wakeupmofoers691]

my stepdad was in aerospace for a long time over eurepe and usa i remember when i took his CASIO 700s 850s series to school the college bound all cultures walks of life kids was all in good times

[@kahuna1247]

"Hewlett Packard couldn't get rid of the old models because they were still so popular..." Oh how times have changed! HP a message for you... Reintroduce the HP50g or provide us with a true successor. The HP Prime does not qualify as a proper RPN replacement calculator for the HP50g.

[@WiltonSilveira]

HP 50g usa a linguagem de programação RPL e a HP Prime usa a evolução do que se usava na HP 39. Isso é um abismo de diferença. Amo a HP 50g e esnobo a HP Prime.

[@thomasmaughan4798]

The HP-35 has been re-issued; it's Chinese i think nowhere near the build quality of the original HP-35. But it is much faster than the original HP-35. For relatively uncomplicated calculations it is great.

[@jenselstner5527]

What a walk through memory lane. Thank you for your insights into HP calculators. BTW, do you know that swissmicros try to make modern replacements for the HP 42S and the Voyger series (especially HP 15C)? Got a DM15L from them and its awsome.

[@ErixCollectables]

You’re welcome! Spread the word because I need some more subscribers. About Swissmicros yes I know and certainly appealing for when you can’t find the originals but luckily I have the originals to play (work?) with!

[@ultrametric9317]

You left out the HP-71B, which was a full-fledged computer which could be programmed in sophisticated BASIC, FORTH, and even Saturn processor assembler. The most advanced calculator up to the 48 series. Also the predecessor HP-75, which was far less advanced. The 71B pioneered surface mount ICs in consumer devices.

[@reinlepiku445]

🥰❤❤❤

[@fabiuspocus1430]

Hi. I am interested in graphical calculators. I see a great collection of the HP48 series, do you have HP49g, 49g+ too? Thanks a lot, Fabio

[@ErixCollectables]

I don't yet have the 49G and 49G+, I am looking for them but don't want to break the bank. Will be interested to find out how the 28-48 have evolved via 49, 50 and HP's Prime calculator.

[@pev_]

I find it slightly disturbing in many videos (incl. this) that show the HP 18/28 "clamshell" calculators, that they never demonstrate why the hinge is unique: not a simple single one but a double one so that you can fold the second half a full 360 degrees to sit on the back of the first (display) half to make it easier for one-handed operation!!

[@ErixCollectables]

Thanks for watching. My video was not meant as an exhaustive review of all these calculators but more anecdotal. But having said that, I have used a hp-28S for many years intensively but hardly ever with the left keyboard fully moved to the other back. The alphanumeric part of the keyboard is simply too important in usage. Also I don’t think the width of the calculator invites you to use it in the palm of your hand. It is too wide IMO.

[@pev_]

@@ErixCollectables Thanks for the reply. It does fit my hand quite well (I have the 28S), and I do not have very big hands :) But otherwise, yeah, I do not know if it was the intent of the double hinge ultimately, thinking from a technical viewpoint it might have been just a way to help the cable going through to not have to twist so much, or maybe to help the calculator be more flat when opened.

[@hifijohn]

always wanted one in high school but I couldnt afford it. I had to settle on sears basically a rebranding of a rockwell.

[@MrWaalkman]

Same here. It was either the log tables in the back of the math book, or a slide rule for me. :)

[@typedef_]

What wristwatch do you usually wear ?

[@ErixCollectables]

I own an Apple Watch. I'm still looking for an afforable HP-01 though. Why do you ask?

[@typedef_]

@@ErixCollectables I was curious what a collector such as yourself would choose to wear.

[@ErixCollectables]

@@typedef_ Ah practicality goes before collectability there. Have to say this is true for most stuff I collect. I use the calculator on my phone instead of the hundreds of vintage calculators I have, and I watch movies and listen to music on other formats more often than laserdiscs or cassettes. I do however, love to listen to vinyl and put the music more in perspective as the artist meant it. That's why I don't collect 'best off' albums. There you have it, the long answer!

[@MarkJones-gt2qd]

Is the 71-B considered a calculator or a computer?

[@thomasmaughan4798]

It is both. I have one. As a calculator it kinda sucks; algebraic entry rather than RPN. As a computer it falls short of almost every other computer on Earth; but it is small and awesome.

[@knudplesner]

So, you don't have the 41 IR modul? Also you should include HP 48GX and HP 50S but not the Prime

[@ErixCollectables]

I don't have the 41 IR module yet. The 48GX is awesome. I haven't had a chance on the 50 yet, is there a 50S?

[@WiltonSilveira]

Acho que ele se enganou. Eu nunca soube de uma 50S, só da venerável 50g.

[@MartinMessmer]

Where is the HP 43S (Prototyp) … THAT would habe been a VERY great calculator too … :-)) …

[@ErixCollectables]

Are you sure Hewlett Packard created a 43S prototype? I have not heard of it. I do know a third party company makes mimic HP-calculators, including a "43".

[@MrWaalkman]

@@ErixCollectables He might be thinking of the WP34S (a flashed HP-30b with keyboard stickers/overlay - which isn't a HP product). And there is the Swissmicros project of the WP43, but it appears that it fell through.
