Although the Ram of a calculator is great because it holds the content even if you restart it, so it cannot be large due to energy requirements.





We can even jump on PCs. Do you know any well known OS for PC that keeps the content of the ram available after a restart (without special "searching" programs)? I do not. You can maybe load 4GB of photos in ram with a PC, but once you restart the system, all gone.

Having devices with much more memory is difficult when they have to run on battery for some days keeping their content.

All this remembers me of this comment: http://bugs.hpcalc.org/show_bug.cgi?id=260 that is funny.

On a side note, aside from loading large data, like photos, that does not require much effort (just use a modern digital camera and suddenly one has large data). Using only programs, equations, plots and so on it is very difficult for me to fill even the 230 kb of available memory of the 50g with meaningful data. I cannot imagine 16000kb for the prime.

I think he misunderstood me. I do not mean to save photos in the Prime as if it were a storage device, because logically could save them in a usb memory; I mean the HP Prime did with the ability to work with photos and images, in fact has some built-in factory, these images can be of nature, physical phenomena, etc. and use them in the application of geometry or statistics, To find a curve that fits for example the curvature of a bridge, or to draw a right triangle on a photo with a tree and that projects a shadow on the ground and things like that; The HP Prime has this capability, so if you use a micro sd card or similar it could be super easy to carry all that information along with manuals and documents and application notes on it because it would not be practical to have to load the computer and the calculator Together to be able to pass files from one to the other. Now, the operating system of the HP 50g is different from the HP Prime, so the programs written in one do not have the same size as the other programs, I also had the HP 50g and is true, 256Kb for the User memory was enough for the type of programs in their factory language, but the HP Prime uses colors and another different operating system whose instructions make a program bigger than 50g. For some reason the 50g were made with the ability to use memory card and not thinking that the user had to use a smartphone or something similar to carry their data. The nSpire of Texas has 100 MB for the user to store programs, photographs, documents, etc for their applications.
