Title: A call to Prizm owners
Post by: gbl08ma on December 11, 2014, 05:36:30 pm
Hello everyone. I'm trying to collect some interesting statistics on Casio Prizm calculators, more specifically:
 - Approximate values for how many of these calculators exist, and how many are usually produced per month;
 - Whether the rate of production has been increasing or decreasing;
 - How long, on average, it takes for a calculator to be bought after being built;
 - Approximate values for how many calculators are sold by country/website;
 - What OS version the calculators run and what is/was the preloaded version;
 - How many calculators exist with each hardware revision, and figure out when each revision was introduced, etc.

To calculate these values, I'm collecting product IDs of fx-CG 10 and 20 models (product IDs, perhaps more commonly known as "serial numbers", even though on the Prizm they are not really serial). These are the sequences of 15 characters printed on the small white sticker on the back of the calculator, along with a barcode, that start with 755.

The first two points should be possible to figure out as long as one has a big enough sample of product IDs. This is because the ID contains the month and year of production, along with the serial number for the month (see more details here: ).
The other points can be a little harder to obtain, but not impossible. It would depend on how much information people have and are willing to share. It's understandable that not everyone is willing to open their calculator to know the hardware revision, for example. Things like the installed OS version or the country where the calc was purchased are easier to remember, but I understand that not everyone is willing to share them (if the project is successful, though, it could be possible to make correlations based on people who shared such information).

To collect the necessary data, tny. internet media has built this website: It is where statistics will be published once we have enough entries for a proper analysis.

It takes less than five minutes (I mean, really. Unless the product ID has become unreadable and you need some more effort to read it) to submit a product ID. Everything is explained on the website.

FAQ (in addition to the one which is on the website):

Q: Turns out my product ID had already been submitted, but I never visited this website before?
A: I already submitted the product IDs I could find on this thread: , along with the preloaded OS version when one was published. If you have more information to add, just re-submit the product ID with more information (make sure to select the correct preloaded OS version, so no information is lost).

Q: I have more than one Prizm...
A: You can submit them all if you wish.

Q: I have one/two/three/... broken Prizm(s). Should I participate?
A: Yes, you can submit all of them if you wish; "current OS version" would mean "OS version it had installed when it broke". Make sure to put "broken", "dead" or something like that in the comments field, in case I decide to exclude those from some statistics.

Q: Is it dangerous/does it bring any problem to share the product ID?
A: As far as I know, no. So far, Casio hasn't asked for the product ID for anything (it's not like with some TI calculators where you need it for a software license or something like that, not sure) and the product ID alone doesn't contain any personal information; depending on the results of the analysis, it could become possible to know, in a not very precise manner, where the calculator was bought (in terms of country/website), but I doubt the information collected will allow for that.

Q: The sticker on mine wore out, is there any way to know the ID?
A: No, as far as I know.

If you have any more questions or concerns, do not hesitate to ask, either here or through the email address listed on the website.

Success! Information associated with the product ID updated successfully. Decoded information:

fx-CG 10 assembled in October 2010. It was the 5355th unit produced that month.

Information associated with this product ID:

Current OS version: 01.03
Original OS version: 01.00
Purchase date: January 2011
Comments: This PRIZM calculator smells like crazy (like most new electronics, but 100 times worse, even after almost 4 years).

Success! Product ID submitted. Decoded information:

fx-CG 10 assembled in March 2011. It was the 57123rd unit produced that month.

Information associated with this product ID:

Current OS version: 01.02
Original OS version: 01.02

I forget when the "purchase" date was, but I got it through the training course Casio held a few years back where the first 300 or so to finish got a free Prizm. :P

Original OS version: 01.00

Are you sure the original OS version was 01.00? Because on you said it was 01.01. The difference is quite important to me, as one of the things I want to figure out is approximately how many calculators got out with 01.00.

Oh wait my bad, it was 1.01. For some reasons the idea that it had 1.00 at first struck into my head, probably because of how early I bought it and the fact my copy still had the Locate bug.

Fixed, now.

Was Picture Plot 1.01 installed along with 1.01 on new calcs?

Picture Plot 01.01 was released with OS 02.00, so there's no way it could come on calculators with OS 01.01. I don't know if calculators that come with OS 02.00 pre-installed have the latest version of the add-ins installed or not.
