HP-80 working like new

This post is for the forum in general. I recently purchased an HP-80 that had a few problems. It was missing a battery, the zero and five keys were not working properly and the on/off switch worked intermittently. Thanks to this forum and the archives, I was able to purchase a battery that works flawlessly and disassemble and repair the keys and on/off switch. I also followed the recommendations for cleaning the calculator before putting it back together. The results... I have a like-new HP-80 that has all of the wonderful characteristics that make the "classics" well - classic. All of this was made possible by the knowledge and experience captured by this website. Keep up the great posts and articles and thanks so much for the good information.

Best regards,


That's good news. Did you peel back and re-stick the label, if so, what technique did you use and how did it work?


I gave some thought to it, but I decided to cut out the holes for easy access to the screws both now and in the future. I know this goes against the purists in this forum, but I don't plan on reselling the calulator and am actually using it at work. If you haven't already done so, I would recommend searching the archives and "Repairs and Battery" section under Collecting & Using for some suggestions on how to remove the label. It appears that people have had success using the techniques described.
