LOL, I would be rich if that was the case.

As a user, I use 8 x HP-41 (1x 41CLv2, 1x 41CLv3, 2x 41CLv4, 2x 41CLv5 & 2x 41CX-HN) for development and testing purposes.

As a collector things are more complicated, you have to take into account the combination of :

• model type (C, CV, CX),
• hardware generation (Fullnut, Halfnut),
• special version (Blanknut),
• box type (small-1st-gen, small-2nd-gen, small-blanknut, wide-1st-gen, wide-2st-gen, wide-blanknut),
• manuals types (ring binding, perfect binding),
• etc.
  

.. and that is why I have so many HP-41.

I am not sure how to interpret this passage.
For my perspective it seems like "here we discuss systems sold between 1968 and 1986, the rest is not welcomed". If I am not wrong (and I hope I am), I can accept that you have this view but I don't agree on it. It sounds too much like gate keeping.

That's a very misconstrued interpretation of that statement and not my opinion. It is because of the calculators that HP produced during the "golden years" that brought many of us here (except the Prime people) but the forum topics are not restricted to only those early models.

One shouldn't be surprised that the newer models aren't the most common among the members of a vintage calculator forum. For that matter, I'd like to see the results of the same poll posted in the Prime forum.

Who cares?

Me, statistics and forum history.

Statistical analysis of the calculator ownership among the members was not how this poll was advertised. My understanding of this poll was to determine which calculators were common, apparently so you could consider showing interest in them.

I believe your methodology is flawed because many people own more than one of a particular model. By your reasoning, if 25 people own a Prime and one person owns 25 41's, then they're equally common, but the Prime is more popular. Shouldn't popularity be a better indication of which models in which to show interest?

Why only working calculators? If someone has a calculator in the process of repair I don't see how that affects the commonality or popularity.

Here's another approach and let's use the 41 as an example.
1. $5000 was recently offered for a rare 41 variant
2. Systemyde created a CPU replacement for the 41 and Diego Diaz created re-programmable modules
3. Angel Martin keeps cranking out new and improved ROM's for the 41
4. SwissMicros created the DM41
5. There's a whole website dedicated to the 41

I don't think these things would have happened if the 41 wasn't extremely common and popular.

SwissMicros has also recreated the Voyager series which I doubt they would've done if it wasn't so common and popular.

Regarding SwissMicros I would really be curious to know how many units they actually manufacture (and sell). Hundreds per year? Thousands per year? I wouldn't be able to make a guess.

Personally I am not really interested in replica calculators although I think it is a good thing they exist. A bit like with paintings - nothing beats a real Van Gogh on your wall (as if I knew...) but a good copy is a hundred times better than no Van Gogh at all

NB: As another entry for the poll/statics I list the calculators lying around my table right now, mostly recent aquisitions, mainly from eBay (as there are very few other sources now):
- Ti SR56
- No name Chinese Memory card reader with integrated calculator (as I also like to collect calculators built into other, completely unrelated! things)
- Aristo Unilog
- Ti SR52 (just resurfaced under a heap of ViewMaster Reels which I also happen to collect)
- Ti 89 Titanium (complete with box and everything)
- Ti 83 plus
- Ti Nspire (first generation with those awkward minute alpha keys)
- HP25
- HP35s
- Sharp EL-W506
- Triumph Adler "Lady" (small stylish "ladies" calculator with green VFD display from the late 70ies)
- Elite 5001T
- Rockwell 24RD
- Adler 81S
- Ti BA III
- Privileg "mini-computer" (boxed, I think this one is really rare, the first and only one I have ever seen)
- Faber Castell TR3 (VFD calculator on one side, slide rule on the other)
- Two do-it-yourself calculator kits from China, one already soldered together, the other in parts

I agree with that. If we count only owners instead of calculators, so far they are only 13 for the HP 41, less than the HP 50g (22) or the HP Prime (16).

maybe he needs a wighted mean between owners and calculator owned

[lemontea]

I know many people are generally interested in vintage electronics, and more specifically in vintage electronic calculators/computers. I probably am in that category, but on a more practical level, if I think back to my original impetus for trying to find HP calculators on eBay, the most pressing and urgent need that I had to satisfy was to find an RPN scientific calculator! (I only had my 11C at the time and was always worried it would stop working or be misplaced.)

Now, in 2017, we have many more options and my feeling of urgency (and worry!) is considerably less, almost non-existent now, particularly with SwissMicros producing great products (I don't consider them to be recreations or copies of HP products. I think they are much improved modern products that have a heritage linked back to the golden HP years, and in the future SwissMicros probably will be as legendary as how we consider pre-Agilent/pre-Keysight HP nowadays, in the area of RPN calculators, especially the HP-style implementations of RPN).

(PS - regarding virtual 41 software, the best is i41CX on the iPhone/iPad platform. Saying it is the best is an understatement. Even the printer paper and ink color are carefully and accurately done.)

"And my fx-9750GII behaves like a fx-9860gII without a backlight"
This means that I should consider fx-9750gII and fx-9860gII part of the same series? Was not the second with SD card?

Yes, and no. This table of Casio calculators (not quite current any more) might explain things a little better:

• fx-7400gII, really light on features. I haven't seen it here.
• fx-9750gII, sold at a cheaper pricepoint ($149) than the fx-9860gII. This is the only one I can find here where I live.
• fx-9860gII, additional features, and a backlight.
• fx-9860gII SD, the same additional features, a backlight and SD card slot.
• ... Others that I haven't included, as they're not part of the discussion.
  

I have the fx-9750gII, which can be flashed with the firmware from the bigger brother fx-9860gII, turning it into a fx-9860gII as far as firmware is concerned, only missing the hardware feature of a backlight. It still looks exactly like a fx-9750gII externally.

To make things even more confusing, the 9750gII and the 9860gII came out in two different revisions (and several colour choices), depending upon what SuperH processor was on their respective motherboards. The earlier revisions of both still had the SH-3, but the upgraded revisions of both include the SH-4A processor and can do stuff faster.

At least HP appears to be somewhat consistent.

Why don't you go for a SwissMicros DM15L? They're easier to come by than an original HP-15C -- in fact their very raison d'être is the rarity of the HP model (Michael's HP-15C gave up the ghost, he couldn't find a replacement so he started a company that makes them). They operate exactly like the HP-15C with a few extras (they run the original HP-15C ROM in an ARM-based emulator), they are much faster, they're reasonably (IMO) priced and built like a tank.

Head on over to http://www.swissmicros.com

Thanks grsbanks!! I have been aware of swissmicros for a while, due to the MOHPC. I think they are amazing making the Voyager series available in such a way!!! I will end up buying one for sure to use it as a "daily driver" and find a HP-15C for collection use. Maybe I can inherit my Dad's 30 year old HP-15C. (99% sure he won't give it up)

On my side of the discussion, Dave Frederickson raises some excellent perspective changing information. My hat's off to you.

[Fred Lusk]

Here is my modest collection, one of each:

HP-35........A hand-me-down from my dad when he bought an HP-45 in 1974.
HP-55........My first calculator purchase, spring 1976, two months before I
................graduated from high school. BTW, I was the first person in my high
................school with a programmable calculator (nerds rule). And, no, a
................calculator on the belt is NOT a chick magnet. :-)
HP-34C......Purchased in 1979, in college (civil engineering), specifically for the
................SOLVE and INTEGRATE functions and because I couldn't afford the
................HP-41C. This is my only non-op HP.
HP-41C......My dad wasn't using this anymore, so he gave it to me about
................20 years ago.
HP-41CX....I had sold my HP-41CV with Time Module and X-Functions to fund
................this purchase.
HP-42S......This wonderful machine has been my daily driver since 1988. 'Nuf said.
HP-48G+...This is a well-built powerhouse, but I am far more comfortable with
................standard RPN than RPL. I also had an HP-48G on loan to my son,
................but it was stolen out of his car. I bought each one new for $25
................because the local office supply store was clearing inventory.
HP-32SII...Another $25 inventory clearance purchase.
HP-10B......I this won in a contest here years ago. This is my only algebraic-only
................calc and my only business calc. Where are the trig function???
HP-35S......I bought this for no particular reason. It sits on my desk at home
................for quick number crunching.
HP-50G......Another purchase for no particular reason. The screen is much nicer
................than all my other calcs, the keyboard feel is OK, but the layout is bad.
................ENTER needs to be where God intended and HP implemented for years,
................which would also allow putting +-x/ in line with the numeric keypad,
................where they belong and not shifted up one row. This one also sits on
................my desk at home for tasks the HP-35S can't handle.
