hp42s locked up Message #1 Posted by bob heffner on 12 Nov 2001, 6:09 p.m.
I have an hp42s which had not been used for about 1 1/2 years. I've just put in new batteries to find it no longer performes the simplest arithmetic functions. I can put a number into the x register, move it up to y, and that's about it. I understand its obsolete, not covered by HP anymore, but does anyone know if it is repairable. Is ther something simple I can do to get it working again? Seems like 7 or 8 years ago is when I got it from hp for trading in an hp45 I had had for many years.
Thanks
BH
