Hello,
My beloved HP-41 CX died today!
It started loosing time and date one month ago. Then making errors with the card reader (stopping in the middle of a card, it was necessary to remove the battery pack to start it again...memory lost and so on...). Then it occasionnaly resetted the time and date and nothing else. Today it just stopped in the middle of a calculation : ln 2 = 0.69 and then no keyboard response...I removed the battery pack, put it back, got some really strange signs on the LCD and it eventually did a memory lost. I started it again but it soon fails...
Any suggestion is welcome!
Thib
