I have and old HP calculator HP 80 that used to work just fine but I cannot find the adapter cord. I discovered that the cord number is 82002A. Does anyone have one of these that I might purchase from them? Or know where I might obtain one? eBay has a few but they are very proud of the adapters.
This forum is realy only for current, or very recent models of calculator. There simply aren't many, if any, people around who can answer questions about "collector" models anymore. I guarentee HP does not have this part in stock for a unit that was discontinued in 1978.
That is a non-HP forum run by collectors and enthusiasts of old HP calculator products. That is not affiliated nor run by HP. Someone there WILL be able to recommend what you can do to find what you are looking for however. You really want to check with someone who knows about these sort of things. I know some models will self destruct and be permanently damaged if you use incorrect power supplies, or attempt to run them without a functional battery inside to name a few issues.
Although I work for the HP calculator group as a head developer of the HP Prime, the views and opinions I post here are my own.
Thank you, Tim. I know that this is a very old model. I was grasping at straws thinking that someone in your following might be a collector and might have what I need. I will definitely check those HP museum collector folks that you suggest. In the meantime, should anything like that cross your path in the near future, hollar out to me, if you would. Thanks for your time. Have yourself a Hewlett Packard day!
