This Vintage Texas Instruments TI-2550 Electronic Memory Calculator includes the original Case, the rechargeable battery charger, the manual, the original battery club card, and even the personal guarantee letter from the company VP with phone number for personal customer service. There are two of the red LEDs that don't appear to work on the far left end of the calculator (see photos). Whether you need this for a movie prop or nostalgic use, this one is bound to please. I have not tested the charger/adaptor. I am including the four AA batteries that I used to test it with. Please review the photos and email me with any questions BEFORE bidding, purchasing, or making an offer. I try to respond as quickly as possible, but please allow up to 24 hours for a response. If you purchase more than one item, let me invoice you with an updated total and combined shipping. I try and include multiple shipping options, so be sure and look at all of them for your least expensive options. See my other listings for more of my items available for sale. For items with free shipping, I reserve the right to change the shipping method while committing to treating your purchase with respect.
