I have acquired in time a number of calculators that I no longer need, most likely because I have others of the same type. From time to time it is necessary to give away some to make space for newer ones! This is my current list of HP calculators that I no longer need.
These are not junk (unless specifically described). All of them work well, again, with the exception of defects mentioned for each individually. Some might have been repaired, worn parts exchanged, old batteries replaced. If I am aware of a defect, I always describe it; certainly any defect clearly visible will be described. If it is not described, it means I am not aware of the defect. If you want more information, ask.
You may find “untested” items on eBay for a smaller price. Sometimes you may even be lucky and get a calculator that is truly untested but actually in good shape. Most of the time though on eBay “untested” means “I have tried everything me, my family, friends and grandmother could think of, and we could not make it work”. You want to buy “untested”? My suggestion is, buy if and only if the seller has a good return policy; otherwise, consider the item as “not working”.
Better / more images are available upon request.
If you do not see something that you would like, ask – it is likely I can be convinced to bundle it, if I can find the item that is. And if you don’t like the price, make an offer – you never know. This is a hobby, not a business, so making money is not necessarily my purpose here. But there are items that are clearly rare or very desirable inside (HP-70, HP-27, two examples) so in the end I might not always be willing to sell for a low ball offer.
All calculators will be shipped from Florida, USA, via USPS. I will use either 1st class package for cheaper items or priority mail. Shipping cost will in most cases be around $10 for US addresses, higher for bulkier items.
Shipping overseas is also through USPS; unfortunately USPS has increased prices tremendously, cheapest package under 1 pound to UK for example is about $27 and insured around $40. Not much I can do here. If you want an exact shipping cost please send me a message via the contact form at the bottom and I will compute.
Canadian shipping may be cheaper, also please contact me.
HP-41C (one) and CV ( five) calculators for parts. None of them power up, some of them are already disassembled. Some of them have an excellent battery contact block . Make an offer individually or for all. More images here: https://photos.app.goo.gl/kASVuukLhhf3uwZP7. Nio port covers or battery holders included but they are available if requested.
HP-45 Calculator (works). Asking $50, AC adapter extra $25. No battery. Battery door in excellent condition,
HP-25 calculator (works) with soft case (case not in the images). Asking $75. Rebuilt sealed battery add $50. AC adapter add $20. Manuals (not in the images) and quick reference add $25.
HP-29C Calculator (works) with soft case (case not in the images) asking $220. Battery case for two AA batteries add $25. Batteries can be flat top rechargeable (NiMh work well, NiCd also) or regular alkaline. Please note that it is somewhat difficult to make good contact with two regular AA batteries because of the raised pole on the regular alkaline batteries.
Rebuilt sealed rechargeable battery extra $50, AC adapter extra $20. I do not recommend to charge the rechargeable battery in the calculator because an imperfect contact may destroy the calculator. I recommend charge the batteries externally or (for the sealed battery) use the recharging dock below.
