My question is this:
I found in my town an Hp 40 g calculator at a very good price, with 256 mb of total ram; it is not considered a very good calculator, but I need to insert lots of data for university exams, so it seems a good choice..and it is also cheaper than the AFX 1 & 2. It seems to me quite strange that the total ram of the AFX is only 144k, while the hp 49 has a total amount of 1,5 Mb of ram (512k for programs in execution and 1Mb for storing programs and data)...so my question is: is the total ram of the AFX (stored data + ram for programs in execution) consisting in 144k or this amount is only for programs in execution end there is another amount of memory for storing data in the calculator?? (the "flash memory (768k)" perhaps?).
My calculator choice will depend on your ideas.
Thank you very much and excuse me for my ignorance in subject....

For me the FX or AFX it?s all you need to do it, of course the CFX are cool for this function too?.

The AFX/FX1.0, has 256kBytes of RAM, and 1MByte of FLASH memory
of this, 144k of RAM is available for user data, the rest is used by DOS for runtime environment
of the flash 256k is used by the system, the rest is available for Add-in applications, or user data backups..
if you want to bring documentation and text on your calc for the exams, the best would probably be to install a text-viewer, and transfer txt files to flash memory. with 768k of flash mem available, that should be enough

less, because of the viewer
question : If we make a viewer that already contains text, compress it with upx could be good for memory, no?

Think it would be better just to compress the text.. can make more effective compression algorithms for text than binary files

yea you can send your 256ko of text and data to the flash and just develop a viewer or just send few txt files you could read with gexII in the flash
with the afx2 you could send up to 700k of data !

but we should improve our viewer, because most of them don't read the carriage return
The ultim solution could be an html viewer but ...
