Classic calculator display chip type number? - Juergen Hofstaedter - 01-21-2013 I am searching for spare display chips for the classic calculator series, for example HP-65. If I remember correctly Hewlett Packard made them themselves, but it would be helpful to know the exact type number for starting a search? Re: Classic calculator display chip type number? - Harald - 01-21-2013 I probably have a spare one. I can check on the weekend.
Re: Classic calculator display chip type number? - Randy - 01-21-2013 The part number is HP 1990-0335. Further information is available here: HP Classic LED Display Information
You need not search the Internet for them, you will not find them as spare parts. Just buy an old HP45 and part it out.
