Details:

I despise corrosion especially with electronics. I inspect all battery contacts of calculators and clean them as much possible so that they are in good working condition. This listing does include the original TI-1890 vinyl case, quick start manual, sealed full a manual addendum sheet, box/shell, and downloadable .PDF version of within. The box's ends are a bit worn but the front and back of box in good condition please review pics carefully.

As a superb and reliable source for vintage calculator parts. Also, I do not give calculator lessons and there is learning curve for any scientific. Display type LCD. It takes more time to list each one but that's because I care.

I have had some unscrupulous airguns buyers in the past who actually removed parts, then claimed was not functioning properly, etc. Even if the calculator is dual power .e. I despise wasting shipping charges. Solar and battery power those batteries are replaced as well.

If I discover anything that might not be working as it should, the listing will include information full disclosure and item likely discounted accordingly. There is no specific diagnostic routine for this calculator that I am aware of. Why buy a vintage or any scientific calculator from me when you might have other choices. Ti-converter-1.

Very good overall cosmetic condition please view pics carefully this one is does have partial wearing off of the square root key and a small spot on cm as per but that's about it. In my experience sometimes this dissipates with actual use instead of dormancy, and other times it simply remains. How do you know it even works then. However, this one does have a bit of annoying key bounce for some the keys, though all keys do function.

Does not necessarily equate to working. If you message me through a listing and ask, I can provide with that information. New ag13/lr44 batteries two installed. Though not an expert, I am reasonably knowledgeable and experienced.

Despise things that don't work properly especially when purported to be working. Works perfectly. Have known working defects that prevent the calculator from functioning as it should those calculators would only be listed for parts or not. Logic algebraic.

Needs new batteries, no or batteries not included really. The ti converter has 194 built-in conversions and was delivered together with the calculator converter handbook that guides step-by-step through common household work-related projects. Listed as used but sold is no display, mention of even if it turns on or much less works. Please see below for this calculators specific features.

I have acquired a tremendous repository of resources, manuals, and information for vintage calculators so can provide some direction to my buyers. I have collected calculators for many years so am familiar with what to look for, has become more valuable, and avoid.
