Hi!

Does anyone know of a keystroke sequence that shows how much Flash-ROM is installed in the fx-5800P ?

I think that it ships with one megabyte. If I install a second chip I would like to know if it is recognized by the calculator's operaing system.

Can user routines be saved to Flash?

Thanks for sharing your thoughts.

Has anyone dumped the flash or found something like a PEEK( function to see what is there?
