HP 25 programming issue - Fouad M. Kaadou - 12-04-2011
Hello,
I have an HP-25 that has a programming problem. When I first received the calculator it did not have this issue.
The issue: when I go to PRGM mode any step I enter reults in a 'GTO 00' command. If I press any of the shift keys the display will show that it is in shift mode but when I click on another key it just puts GTO 00.
Any ideas?

Hi,
you have a 25 with a bad RAM chip.
The only source of spare parts is another 25 with other issue.
HTH.

Tkanks Ignazio. Do you know which is the RAM chip so I can make the transplant?
