Greetings from Austria!

The 35s is a nice calc. I have two. I’ve never used a 25 but it looks solid.

HP48GX, HP42s and DM42.

I added a 50g and a 41CX to my collection. I updated my original post in this thread accordingly.

Hi,
I also make here my contribution.
It also seems to me that I am set in the trend ...

HP :
1 x HP48GX (S)
+ 1 x HP48G (S)
1 x HP41CX (S)
1 x HP12C (A)
+ 1 x HP12C Platinum (PHA)
2 x HP15C (2 x A)
2 x HP17BII (S + ID)
1 x HP35s (PHA)
1 x HP27S (S)
1 x HP11C (A)
1 x HP16C (A)
2 x HP10B (S + ID)
1 x HP10BII (CN)
1 x HP10bii+ (PHA)

TI :
TI-66
TI Galaxy 67

Sharp :
PC-1251

Casio :
FX-602P
FX-4000P

For information, the 3 PHA made are the ones I daily use now. None of the 3 keyboards resembles the other!
And certainly do not compare to the keyboards of the 80s and 90s generations. However, in order to avoid typing problems with no effect, I am very careful to press the keys perpendicularly!
Otherwise I adopted them for their comfortable memory and the wide range of their functions.
Practically all in one!!


2020-07-06 - Updated to insert the forgotten HP11C !!

RE: Most common calculators in the forum?
Not a collector myself.

HP:
50g (black, bought new, extensively used)
50g (black, bought used in mint condition)

Non HP:
Casio FX-4000P
Casio CFX-9850G

Both Casio calcs were bought new and extensively used as well.

The first post needs to be updated.

It's amazing to see people with more than 100 calcs. They must have a Calc Room at home.

RE: Most common calculators in the forum?
Here's what's in my collection currently:
  • Casio fx-115ES Plus
  • Casio fx-991EX
  • Casio fx-9750GII (with fx-9860GII firmware)
  • Casio fx-9750GIII
  • HP 15C
  • HP 35s
  • Sharp EL-506D
  • TI-36X Pro
  • TI-89 Titanium

The calculator I've had the longest is the 15C. Unfortunately, I didn't know what I had until years later after it had already suffered damage in multiple moves. Despite its rough shape it does still work, except for a dodgy ENTER key. Until very recently with my purchases of the 40gs and the 48gII, it was the only calculator I have that wasn't purchased brand-new.

The Sharp EL-506D is the one I've had the second-longest (it was bought just a few months after the 15C) and it's the oldest calculator that I had bought brand-new. It was a NOS item bought on clearance in a local store. Somehow I managed to keep it in excellent condition, and even kept the user manual, despite having gotten it over 20 years ago.

The 35s gets the most use of the bunch due to school, followed by the Casio fx-991EX. I've tried to stick with NCEES-approved calculators even when not strictly required by a class. I also try to make sure I can use multiple calculators since it both makes sure I am learning the material and that if something happens to one calculator just before an exam I can readily switch to another. Still, I definitely favor the 35s due to RPN as well as its functions and programmability.

Edit: Removed "on the way" calculators.

RE: Most common calculators in the forum?
I never intended to collect calculators but I started out with a few Casios and TIs which I used for a while. The TI59 served me well until it broke and I discovered the HP32S which wore out after a few years. Replaced that with an HP32Sii, and then a second 32Sii when the first one gave up. Later started using an HP11C and lastly an HP15C. I now find that Free42 serves all my needs (on the phone, tablet, and PC) so I've given up using my 32Sii, 11, and 15, but I am considering getting an MD42 just for kicks. I never had any particular use for graphing but I recently picked up an HP Prime which I haven't gotten around to trying yet.

RE: Most common calculators in the forum?
In addition to the calculators in my previous post, I have gotten the following in these past few weeks:
  • HP 17BII
  • HP 32SII
  • HP 40gs
  • HP 48gII
  • HP 49G

All of them are in very good physical condition, with the 40gs being brand-new.

The 32SII did have an issue with dim elements on the LCD. It was disclosed in the listing and I knew I was taking a bit of a chance. Fortunately it turns out there was just some dirt on the foam connectors between the mainboard to the LCD panel. Thanks to searching around this forum I was able to take it apart and repair it.

RE: Most common calculators in the forum?
Hmmm, let's see...this is the stable so far:

HP-15C x2
HP-16C x2
HP-45
HP-65
HP-35S
HP-50g

I'm probably on the young side for the demographics here...I used that 35S and 50g throughout school. Got started collecting vintage HP calcs in grad school actually. I don't believe I ever met another student who used RPN. Everyone either uses TI (for exams), their phone, or a computer. I have to admit that I rarely want or need the 50g's graphing when I can use matplotlib on a computer instead. But I regularly use scientific functions and I really enjoy having the 16Cs around for that kind of thing.

If I had to bet, I would say the 12C but if someone has the figures, I'm interested.

RE: Most common calculators in the forum?
Current holdings:

28S
48G
35S

Recently re-homed:

11C
15C

I guess I just like the newer calculators. The 11/15Cs were nice to hold and hack a few programs on, but once I found RPL (on the 48G), I was hooked. The 35S was just a "let's see what this is all about" purchase. I did formerly own a Prime but it was an early unit and I just couldn't read the orange text on the keyboard so it moved on.

Well I don't know the sales figures but to get an idea of the popularity of the different HP calculators I took a snapshot of all HP calculators auctions posted on eBay in the Vintage Calculators section on September 2nd.

It took me sometime to clean up the data to keep only the auctions related to calculator units and not to peripherals or docs, and to map the auction titles to model names but in the end here is what I get for a total of 516 calculators on sale:

1st, the frequency of the different models, as expected the 12C is the most popular:

   

2nd, if we group by family: all 12Cs, all 41s, all 10Bs (B,BII,BII+), all 48s, all 17Bs (B,BII,BII+) .... the 12C is still ahead of the game:

Excellent, thanks for doing that (a lot of work!) and sharing it here Didier!! Smile

What is your biggest surprise in the results? (Everyone, please reply)

For me:

Surprise #1: The large number of 17B and especially 19B models available

Surprise #2: The relatively large number of 15C models available

RE: Most common calculators in the forum?
Currently have:

HP

HP-12C, bought new in 1988 and still going strong
HP-21, recently acquired for parts but now working perfectly
2 x HP-25, both working although one was bought for parts
HP-29C, not working, being converted to an HP-29E LP
HP-41CX, working but case needed repair

SwissMicros

2 x DM42, one now running WP43C firmware
DM41X, recently acquired so that the HP-41CX has a quiet life!

Will probably sell the HP-21 and one of the HP-25's soon and will update this post accordingly.
