So once again if it people won't need it anymore, would sell it (getting quite some money back). Otherwise even if a calculator is not used, there is something planned for it.

Being old is not problem. The old calculators tend to have good build quality, and if you go back to the early days of the HP-41, they were even built to be repaired, not tossed away and replaced (as a service measure).

Speed is also not so relevant. Most things done on a calculator are done by hand calculation and if it can keep up with me typing, that is good enough. Programs are used, but I can often wait a while from time to time, if needed.

Just like any tool, what matters is whether it helps me solve the problems I have at hand, without annoying me.

Having said that, I can also appreciate the engineering that went into it and its historical context.

RE: Most common calculators in the forum?
So, while everyone was chatting about who has the bigger calculator collection (lol --- I think there is just some minor difference in culture)... I managed to get one of these old babies:

https://imgur.com/gallery/Nk7KB

So you can add 1 x 42S to my collection (the others are just calculator porn. Nobody I know, except you folks, will appreciate my photos).

To answer what is the purpose of this forum/thread (not asked, but just my 2 cents), it is precisely for the reason that I am able to, today, share my joy of acquiring a 42S, with people who appreciate and understand it.

Certainly my wife doesn't, and also she doesn't need to know! LOL

That reminds me, I have to get rid of the shipping box soon...

And someone mentioned some OTHER calculator "things" in their collection. Well, I didn't mention I have one of these also (it still works!), but probably not necessary to add it to the ongoing list:

[UPDATED link with correct model, Casio TC 500, not 600]

Now, on a totally separate but sort of related topic... It's December! Hope to add a DM42 to my (our) collection(s) soon!

RE: Most common calculators in the forum?
Hello!

(12-01-2017 05:58 PM)pier4r Wrote:  Nonetheless I assume (I may be wrong) that the majority bought this or that model to use them even if for limited time.

The following calculators I bought (or got bought whilst still at school) with the intention of actually using them - and of course I did use them then:

- Privileg 883 D-ESR-E (very colourful scientific calculator with green VFD)
- Ti59
- Ti30 LCD (cheap replacement while the Ti59 was away for repair)
- Aristo Aviat (mechanical)
- ASA CX-1 Pathfinder

Back in the days when I really needed a calculator (school&university) HPs were outrageously expensive compared with everything else and therefore I never could afford to buy one for actually using it. Now I can buy them but there is nothing to calculate... But that is a different topic about which we had several threads already and the reason why HP lost the education market in Europe, besides RPL of course.

Regards,
Max

NB: And for your HP41 statistics count me in with 2xHP41, 1xHP41CV and 2xHP41CX. All of them working. At least when I tried last time.

Exactly what I was thinking. I suppose Freud would call it "calculator envy". Smile

I find it interesting what people have in their collections. I'd really like to know what HP-Collection has in his. I know he has a few Curtas, which are missing from this list.

Another approach in deciding which calculators are common/popular/interesting is to consider which calculators have had recent after-market options designed. Or, How to Have Even More Fun With Your Favorite Calculator.

HP-41
* Clonix and NoV modules by Diego Diaz
* 41CL CPU board by Systemyde
* 3D-printed parts by Nate Martin and others
* DM-41 by SwissMicros

HP-42S
* DM42 by SwissMicros

HP-48
* FRAM memory modules

HP-71B
* FRAM71 memory module by Hans Brueggemann

Speaking of the 71B, I was disappointed to see the 71B supporters not chime in, and I know who you are! Between three of us I know we have 29 x 71B's.

Anything HP-IL
* The PIL-Box by J-F Garnier

Voyager Series
* DM Series by SwissMicros

Woodstock Series
* new ACT by Panamatik
* Woodstock Low Power by Panamatik
* NP-25 by Chris Chung


Items from my collection
1 x HP-35 - Had it since '73
1 x 35S - Tribute to the 35
2 x HP 50g - One blue
1 x 48GX - Black screen
10 x 71B
1 x Xpander - New to list

You got the bigger one ;-)

I only have 3 x 71B and 2 x 75 (one C and one D). And a Curta Type 1. Type 2 high on my wishlist but outside financial reach.

NB: Has the HP-01 been mentioned yet? (1x Stainless steel, working, 1x Gold plated, working, 1x Gold plated, dead). Or the wonderful and rare HP-10 and HP-19C? (two each, all working apart from one dead printer).

I split the devices because I know that:
49g+ had a bad keyboard reputation
48gII and 49g don't have the SD card.

therefore if you look in the first post you find:
6 x 48gII/49g (DavidM, P.Berger, 2 x D. Hayden, 2x J Horn)

If one would count the 49 series together, they would be first, above the 41 series.

@edS2, updating.
ah ok, I did not see "49g" after "48GII" Smile

Hardware: Hp48S - Hp50g (5x black + 1 blue) - HP39gII - Hp27s - Casio fx-CG50

Some were purchased for the modules and will be sold. 10 is too many for me, plus, someone else has 11.

Perhaps a working 3D-printed Curta.

Hi Masimo,

I was aware of Meindert's contribution, but I did specify recent options as that is where most of the activity and interest lies.

However, for a dinosaur I suppose circa 2000 is recent. Smile

I know that. My first HP-71B had nothing, so I needed to buy another one to get some modules (including the legendary MATH ROM of Valentin Albillo fame). But it still had no card reader so I needed to get yet another one... A wonderful machine that can control a whole laboratory if necessary, but as a pure calculator it is a total loss unfortunately. Otherwise I may actually use it every now and then.

So to say a Swiss Micro in reverse! That would be a post retirement project as I have a 3D printer and know how long it takes to fabricate all those parts.

Max

NB: Was the HP-38G yet mentioned? Allegedly the worst calculator HP ever made and therefore a _must_ for every collector.

It was so much better than anything else, so revolutionary, it was almost shocking. I imagine TI engineers sighing in dismay when they realized that HP was shipping a product that was better even than what they, TI, only had on the drawing board.

At that time I'd been a young first officer (aka Copilot) on a Boeing 707. Long range flight planning was done by looking at about 500 pages of structured numbers. With an HP97 I statistically evaluated all these numbers and finally ended with a magical formula for my HP41C. Then I could select from the various variables take off or landing weight, the fuel available or necessary, the wind component or feasable -- which of the remaining data I'd like to calculate. This was somewhat easy to progranm on the HP41 with those specific flags for input or not.

I was asked to provide this programme for a TI59 also. I failed to do so, as on the TI59 a completely different approach would have been neccessary. And I was not overly willing in doing so.

There's a time-lapse of the Curta being assembled starting at 7:50. An amazing piece of work.

Yes, I should have included the MLDL2000, but then the 41 was winning the "option race" and I wouldn't have been able to get in the joke with Massimo.

So, Sylvain, you have an extensive HP collection. Which models do you consider common and/or popular?

Same here. My father first showed me his HP (15C I think) calculator when I was a kid, and I loved how I could calculate things fast with it. Later in school we had a little calculator rivalry in the nerdy part of the class. One group (well, me and a friend) were diehard HP fans, while the other "group" (two other friends) preferred Casio and TI. My loyalty to HP has sort of stuck Smile
