HP 25 -> HP25C



#4

Hi all, I'm wondering if it is possible to turn an 'ordinary' HP 25 into an HP 25C. Can it be done?
Thanks, Vic

The easiest thing to do is drop a 25C circuit board into a 25 case/keyboard. Otherwise you would have to mount the 25C RAM chip onto the HP25 circuit board and modify the power supply, etc.

ha! on the ti-57 you could do this in software :-)
