Do not take this the wrong way please. Is this a factory picture? If this is a factory picture, is it the same exact one as pictured? Only asking to see if the manual can be downloaded online. Fanned you, great auction.
No worries Babaytaz, I completely understand. It is a photo of the Internet that I chose which is exactly like the actual calculator. (I do have the book but it is at another location and I am unsure when I will be able to get over there.) It is a dark gray, with a combination of light gray and dark gray buttons with white writing on them. It is called the Business Analyst if that helps at all. It has a small laminated type card that fits in the cover which gives Time-Value-Money Calculations, and Promted Worksheet Display Indicators along with Prompted Worksheet Key Sequences. SN is S-1206F and the website listed on the back says education.ti.com which might offer a book there. Hope this helps you. =)
