HP 25 -> HP25C Message #1 Posted by Victor Koechli on 18 July 2003, 7:54 a.m. 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

Otherwise you would have to mount the 25C RAM chip onto the HP25 circuit board and modify the power supply, etc.
