This is a copy of "Introduction to the iAPX 286" from Intel. It's an technical introductory blurb targeted at hardware designers to get them interested in using this chip, better known as the 286, in their designs. That chip debuted to the mass market in IBM's PC/AT. This copy is in good shape with a bit of shelf wear, mostly in the form of little spots of white paper showing through where the black ink wore off.
