First produced in 1970, the 16-bit PDP-11 minicomputer was one of DEC's most successful mid-range minis. Like the PDP-8, the PDP-11 was employed in a wide variety of business and academic sectors, used in various real-time applications and had a very long production span (1970-1990). Although the PDP-11 was much larger and more expensive than its "predecessor", it was a more advanced design and easier to program. In all, over 40 models of PDP-11 were produced; from the large, early and iconic Unibus models, to the smaller Q-bus models, the PC-sized Professional series, to special purpose designs like the MINC-11 laboratory system and various DEC terminal systems. | First produced in 1970, the 16-bit PDP-11 minicomputer was one of DEC's most successful mid-range minis.

A number of unofficial clones, mostly Soviet and American n origin, were also created. | ||
While the PDP-11 was a success in and of itself, it also influenced many other systems. The Motorola 68000 was inspired by its design, and the DEC VAX is a direct descendant. On the software front, native PDP-11 OSes inspired popular microcomputer systems to come - in particular, CP/M and DOS. The language C is said to have been influenced by the programming environment of the PDP-11, and it was the second computer to ever run Unix, and the first system that launched it to stratospheric heights of popularity. | While the PDP-11 was a success in and of itself, it also influenced many other systems.
