Classic HP Calculator Repair Experiences

[GreyUser]

Just my opinion but...

If you intend to use it, repair it yourself, unless of course you have absolutely zero electronics ambition. There is documentation on the web and plenty of support here on the forum to get that done. Yes, the first time can be challenging but I guarantee you the experience will be enjoyable and interesting.

If your goal is to sell the units, do that as-is. Repair is by no means a sure thing and you’re not likely to get the additional investment back in the sale price, especially so for the HP80. One last bit of advise is don’t be fooled by eBay buy it now prices, they don’t reflect market value in any way.
