Repair on Hp 45c

[Jim Anderson]

I am a surveyor who has been using Hp 45c's for 40 years to add degrees, minutes , and seconds and to convert degrees , minutes and seconds to decimal degrees in order to take the sin of the angles. i have developed some hot keys with ASN function. My Calculator has gone down, i bought another on ebay and it will not work. I need someone to repair one or both or take parts from both and make one. Can someone direct me to someone who could do this for me. I am new to this forum so you could email me at jima@andersonlandsurveyors.com. thanks! Jim
