HP42 Malfunction Message #1 Posted by Paul W on 3 Nov 2003, 2:50 a.m.
would anyone have any ideas concerning a work mates HP42 which is playing up.
a brief history of his troubles follows;
HP42 batteries went flat causing it to crash. new batteries were inserted, without causing the loss of program memory.
The calculator now inserts a series of zeros (about 6 or 7) before any other number which has been typed usually leaving only enough space for a single digit.
He hasn't tried any of the self testing procedures (he will when he finds his manual) nor has he tried the resetting procedures yet (but he will)
any thoughts or ideas would be welcomed.
regards Paul W
