Details:

How do you know it even works then. Capable to edit statistics finding mean, SD and variance calculate permutations, combinations factorials at the push of a button. I have collected calculators for many years so am familiar with what to look for, has become more valuable, and avoid. I have acquired a tremendous repository of resources, manuals, and information for vintage calculators so can provide some direction to my buyers.

Obviously have been abused by the previous owner FYI I am second owner of this calculator listing unless specify otherwise. Have known working defects that prevent the calculator from functioning as it should those calculators would only be listed for parts or not. Good cosmetic condition please view pics carefully this one is nearly. Even if the calculator is dual power .e.

Converts data to and from degrees, minutes seconds, plus can solve in complex mode as well. Simple to use scientific calculator with protective cover. This calculator is perfect for the student,or anyone who wants to solve math and science problems, or any complex figures.the Hp9s handy anything, use it add up bills, metric conversions, calculate currency exchange. Does not necessarily equate to working.

New batteries installed. I despise things that don't work properly especially when purported to be working. Solves trigonometry and inverse functions. Solar and battery power those batteries are replaced as well.

If you message me through a listing and ask, I can provide with that information. It takes more time to list each one but that's because I care. Works in a variety of system modes rectangular or polar, also degrees, radians and gradients. Though not an expert, I am reasonably knowledgeable and experienced.

And can edit statistics, calculate permutations, combinations and factorials. Has memory functions for storing and retrieving data two clear options. As a superb and reliable source for vintage calculator parts. It comes with 6 common metric conversions.

Needs new batteries, no or batteries not included really. This listing includes an original Hp hard case and a HP-9S quick-start guide please see pics. Also, I do not give calculator lessons and there is learning curve for any scientific. Enables fixing number of decimal points displayed, making it easier to manage/understand the solution or work in engineering mode if needed.

Solves trigonometry and inverse functions. I despise corrosion especially with electronics. Listed as used but sold is no display, mention of even if it turns on or much less works. Decimal point selection.

Works perfectly. I inspect all battery contacts of calculators and clean them as much possible so that they are in good working condition. It was later replaced by the Hp-10s. I have had some unscrupulous airguns buyers in the past who actually removed parts, then claimed was not functioning properly, etc.

If I discover anything that might not be working as it should, the listing will include information full disclosure and item likely discounted accordingly. Quick and easy metric conversions for various measurement number system. Please see below for this calculators specific features. I despise wasting shipping charges.

Why buy a vintage or any scientific calculator from me when you might have other choices.
