hp01 wrist calculator


The hp 01 wrist calculator I have purchased in 1978, has been stored for more of 20 years, in safe conditions, the batteries having been removed prior to the storage. I have now tried to restart it using the required power source (Ucar 357 Silver oxide batteries). But the behaviour is quite erratic, and I have no idea about the right thing to do. Could someone suggest me some useful adresses in order to repair it? I apologize for my very poor english!


There is a tiny little reset button that you must press after changing the batteries (some models may have two pads that you have to short together with tweezers). The manual is on the HPMUSEUM disk set.
