Description: National Semiconductor NS199 Calculator with original case & new batteries.Business card sized, with case it is about 4" x 2.5"Good pre-owned condition.Tested and working with some light marks and scratches from previous use.Note: I noticed a potential flaw in the screen. I might just be doing something wrong, but you can see the marks in the extra photos.Operates using 2 button cell batteries - just replaced. See photos of which batteries it takes.Includes original protective leather case.Please see pictures for more details.There is one screw missing inside for holding the batteries in, however the one remaining screw seems to hold them in just fine. You may be able to replace with a tiny eye-glass repair screw, but I didn't have one. I put new batteries in, turned it on and ran some calculations to ensure it is functioning. I did notice an extra mark in the LED however. Not sure what that is all about, but it did not seem to effect the calculation. From the Smithsonian's web page:DescriptionThis credit card-sized calculator has a metal case with twenty-three rectangular plastic keys and plastic trim. The keys include ten digit keys, a decimal point key, a total key, four arithmetic function keys, and four memory keys. In addition, the calculator has an off key, an on/clear entry/clear key, and a % key. Above the keys, on the left side, is the eight-digit LCD display. A mark below it reads: NSC National Semiconductor 199. Left of the display are three circles.Text at the bottom of the back reads: NATIONAL SEMICONDUCTOR CORPORATION WEST JORDAN, UTAH 84084 MADE IN HONG KONG. All of my items come from auctions, estate sales and thrifting. I do my very best to describe and care for these treasures until they come to live with you. As a reminder, these items are not new, and may not be in perfect condition. I photograph and/or mention any imperfections in my listings, however, sometimes I do miss things. I do not scrub items to clean, as I leave most restoration to the buyer. That way, you'll be as gentle or harsh as you feel is safe for your piece. I barely even wiped this one off, so it will arrive with some original Las Vegas dust. Please view photos thoroughly, enlarge if needed, to really get a good look before purchasing these vintage items.
