This is a lot of vintage manuals and books for the VAX 11/780 superminicomputer from DEC. This sale includes 4 loose books, 10 or 11 sealed books or short guides & possibly other related papers, and a cardboard DEC Educational Services book box. The loose books include a VAX 11/780 Technical Summary, Hardware Handbook (1978-79), Architecture Handbook Vol. 1 (1977-78), and Software Handbook Vol. 3 (1977-78). I'm not sure which guide books are included, nor if there are any duplicates inside, though the top book is Introduction to VAX-11: Concepts (Student Guide). The loose books are in pretty good shape overall with some light discoloration, bending, cover wear & tear, and edge wear. The DEC box is decent though has some staining and other storage/age wearing.Please ask if there are any questions.
