Oh, here are the first ones I forgot:
DM15C
DM15L

Next edit:
There is a Sinclair scientific programmable waiting to be picked up at a friend's house next time I visit the UK

And of course 3x WP34S an 1x WP31S

Clamshells! I must not forget those. HP28S and HP28C, one each.

[EmmanuelC]

Main used: HP 12c 50g 32SII 71b - WP34s - Sharp PCG850V

Still in my drawers: various HP (34C 41CV...), few TI Sharp Casio and Elektronika.

I like the (rich) in-the-pocket sizes of the 12C and 32SII; I like the fabulous power of the three big ones; I am a fan of the WP34S’ complexity...

1. A novelty calculator. A desktop ruler with a vey basic solar calculator that is actually the lid of a box for a selection of Post-its. (eBay, 1€) - everybody has seen it on eBay dozens of times I guess:

2. Another novelty calculator. Reflects one of my true passions (calculators are only a secondary passion I'm afraid). The calculator itself is so boring that I didn't bother to replace the empty coin battery. The little label with the horse's stable unfortunately has become unglued. Need to keep looking for a perfect one :-)

3. This curious 2/3 scientific calculator which has square root, Pi and logarithm but no triginometric functions. Labelled as "MBO", a German company, but certainly made by someone else:

4. The already mentioned in several posts HP-49g+ into which I didn't even bother to put batteries for the photograph because I don't like it in the least:

5. An older variant of a Ti-83 (again, too lazy to put batteries inside):

6. A newer variant of a Ti-83:

7. Triggered by this thread here http://www.hpmuseum.org/forum/thread-9787.html I got myself a Commodore PR50 to fill a gap (PR100 I have several already):

8. And this one is the crown jewel in this list. Arrived in the mail today from the UK. If you thought red LEDs are a wonderful thing - as I do - then you have not seen a Panaplex display yet. As I have not been able to see the electroluminescent display of the Apollo Guidance Computer's (AGC) Display and Keyboard Assembly (DSKY) in real life, which is probably even more incredibly beautiful, for me that orange gas-discharge display is the top of the world. The calculator itself, a Berkey/Omega 100 is a mere four-banger with the only addition of a fixed-decimal-places switch. But turning on the power will instantly throw you back into the Apollo era! It takes 2-3 seconds until the inverter inside that unusually heavy little calculator (about the size of an HP Woodstock but twice as massive) has generated enough high voltage to "ignite" the Neon gas inside the rightmost "0". So wonderful. How ultra incredibly wonderful would a "Woodstock low power" with a Panaplex display be - I hope the right person is reading this :-)

Thanks for sharing. Nice set of pictures.
Panaplex displays will always be my preferred display technology for the quality classic looks.

[Maximilian Hohmann]

More items for the statistics have arrived in the mail in the last two weeks:

An HP-37E, advertised as defective, in excellent condition but with some internal connector problems which only show once it has been running for a few minutes:


A Ti-31 solar, a variant of the trusted Ti-30. Indestructible, no battery - just a solar cell and a capacitor, these things will definitely survive mankind. Does everything one needs to do with a calculator apart from programming:


A Ti-83plus. I lost count on which ones and how many of each of those I already have. If they sell for less than 3 Euros I buy them. Somebody hand-painted the worn parentheses keys. Whoever used this calculator before me should have bought an RPN model if he needs so many parentheses!


And now some bells and whistles, or rather colour and sound:
A blue Ti-82 stats. 1 (one!) Euro. Perfectly working and much nicer blue than that Hp49:


Another Smarties calculator. They come in two sizes and many different colors. This is a large blue one:


A musical calculator from Casio, the ML-81. Including clock, alarm and stopwatch, unfortunately it can not work with time values like other Casios. The display has a little stain from some liquid but the calculator works (and plays music, albeit only one octave):


And this one here belongs in every collection: the Disco Calculator! Colored light and disco music from every key pressed. I got it from France, but of course it was made in China. Recently I drove my wife mad by doing some actual calculations with it. The little video below is unedited and not very good but I hope that watching it will boost the sales of the woderful Disco Calculator!

Hello!

And another entry into this thread which will shift the "most common" statistics a little bit away from HP products - as I have been unable to find any affordable ones for my collection during the last few weeks.

But I found (and/or was given) some other calculators worth mentioning and counting into the statistics:

A Ti-nspire, second version, with the exchangeable keyboard:


A holding pattern computer (which must be one of the most useless devices containing "computer" in their name ever made. ):


An Airtour CRP-1 circular slide rule navigation computer. Very substandard build quality, especially compared to the competition of Aristo.


An actual HP item, a 4k memory module for an HP-71B. Another module is still in the mail, a Navigation pack for the HP-41:


A little collection of banknote-calculators which must have been en vogue in the 1990ies if one can tell that from the currencies, some of which have been replaced by the Euro in the meantime:


And this is the calculator side of the 100DM banknote. Who has ever thought about Clara Schumann again after exchanging his last 100DM bill for 50 Euros?


A Ti-92plus. Big thing! I already have the non-plus Ti-92 and it's successor, the Voyage 200:


A Sharp PC-1403H. With a dedicated "Matrix" mode that must make it somewhat unique I guess:

[Maximilian Hohmann]

... part 2 ...

One of the legendary masterpieces of industrial design by Braun, a type 4 777. A child of the 1990ies but the basic design has been around since the 70ies:


Another rebranded Casio school calculator, this time under the name of a once famous German typewriter manufacturer of which only the name remains, called Olympia LCD-8310:


Not yet a calculator, but maybe the heart of a future one, a Raspberry Pi (5 Euros only!). If one would remove the large connectors and add a small display (OLED maybe?) it could just fit inside a Woodstock housing...:


Here is one of the few non-HP RPN calculators, a Privileg SR 54 NC. The "NC" part is not working any more, but the rest is just fine. It displays a wonderful lightshow for almost a second when computing transcendental functions. For that alone it is worth having one:


And this again is not a calculator but was made by HP and can be convertred into a USB infrared receiver with one of the Arduino mini boards following Martin Hepperle's instructions in this forum:


And here comes the strangest novelty calculator I have come across in 30 years of collecting. An electronic (toy) microscope from China calling itself "Dr.Mike" which was obviously built around the hardware of a mobile phone (camera, screen, USB interface, SD-card interface, FM radio, you name it). It's menus still have all the functions commonly found on a phone, many of which make absolutely no sense in a microscope:


Especially the calculator - called Kalikulator! - which can be operated only with three buttons: left arrow, right arrow and enter. Adding 1 and 1 requires 49 key presses (I really counted them!) which must be the all time record for any calculator:

That series of machines was underrated IMO. I also have a TI-92, TI-92+ and Voyage 200 (I'm just missing the TI-92II to complete the family). Despite having a CPU running at "only" 10-12MHz, they're still quite quick. The 92+ and 200 can also be programmed in C and MC68k assembly with tigcc. Hours of fun

The thing that always astounded me was the fact that the TI-89 and the TI-92+ are virtually identical when it comes to specifications and their abilities (they even share the same manual), but the TI-92+ wasn't allowed in examinations simply because of the QWERTY keyboard. The same is true of the TI-89 Titanium and the Voyage 200, although they don't share the same manual.

[TheKaneB]

Yeah, the Voyage 200 is probably my non-HP favourite! Tons of possibilities for programming.

I picked up a Voyage 200 on a whim and it is very nice to use the qwerty keyboard is large enough that I can type on it comfortably, and since it is a qwerty arrangement I hunt on the keyboard less than I do on a keyboard arrange in alphabetic order. I got a Nspire touchpad about the same time and the alpha keys on it are so tiny I have to use the eraser on a pencil to push them, but I still think it is better than the click pad keyboard, to me that looks like a disaster.

Reminds me of a book I read in the original Portuguese when I was 14. Quoting from The Man Who Counted:

Quote:“Let us multiply now by three:
142,857 x 3 = 428,571
“Once more, notice how curious the answer is. Its numbers are the same ones again, but in a different order. The 1 that was at the left has moved to the right; the other numbers stay where they were.
“When we multiply by four, although the numbers shift position, they remain in the same order:
142,857 x 4 = 571,428

[HP1528484950]

Owned and functional
1 x HP6s Solar
2 x HP12C
1 x HP12C Platinum 25th Anniversary Edition
1 x HP15C Limited Edition
1 x HP17BII
1 x HP35S
1 x HP49G
3 x HP50G
1 x Prime
Today the Prime is my most used calculator.

Regrettably sold to buy the next one when I was a student: HP28C, HP28S, HP48G
Previously owned but did not last (keyboard issues): 2 x HP49+
In storage but not really operational ("inherited"): HP45, HP33E, HP34C, HP41C

I was to young to have it but I dreamed of the HP71...what a beautifull machine !

This one's a dead ringer for the fx-82TL but the history scroller has the look of the MS (next generation after TL). I've no idea if that calculator has a full history browser of ten entries (the MS) or just the last calculation (TL and possible predecessors).

Could you do a simple test for me on that Olympia? Check what happens if you go upwards more than once, do you continue up the list of past entries?

Just tried it: It only lets you see and modify the last entry. There is no way to go up to previous entries. From a distance he "control wheel" looks like a four position switch but it only operates left and right.

I did not forget this thread. Just I don't find the willpower to update the first post. I will do it eventually.

Note that one can update the data collaboratively on the wiki, here:
http://www.wiki4hp.com/doku.php?id=forum...calculator . I update first the wiki, that is versioned, and then this post to avoid mistakes and lose everything

Then it's definitely a fx-82TL clone. I figured as much when I only saw a left/right on the control "wheel". I wonder how many other companies did complete—or almost complete—copies of some fx-82 model. I know HP used the 85MS as a model for their HP-10S and 10S+.

Not sure about the 10s but for the 10s+, they didn't use the fx-85MS "as a model", they used the fx-85MS itself. It's a Casio board inside the 10s+.

Casio have sold OEM boards for as long as I can remember. Even full OEM calculators with someone else's label on them.
