Re: HP-25 turns itself off Message #2 Posted by Geoff Quickfall on 14 July 2009, 6:28 p.m., in response to message #1 by Des McPherson
I would like to say that entering five '7's in a sequence or over the 10s display is the "secret off code" for the HP 25 but I can't!
Sounds like a memory and display problem. The x register is a memory. Did any of the other keys when entered five times in a row or any sequence of five presses over the 10s display cause a similar fault. Also try:
388885 ENTER 5 /
this should develop 77777,
Does it turn off when it generates the 5 sevens.
Cheers, Geoff
