The PDP-11 was the most popular 16-bit minicomputer. Introduced by DEC in 1970, it remained in active production until 1996. The PDP-11 family included many processor designs (photographs courtesy of Digital Equipment Corporation):
- 1970: PDP-11/20 - first design (also PDP-11/15)
- 1972: PDP-11/45 - first design with memory extension, instruction and data space, floating point (with fast bipolar memory, PDP-11/55)
- 1972: PDP-11/05 (also PDP-11/10)
- 1972: PDP-11/40 (also PDP-11/35)
- 1975: PDP-11/04 - first single board design
- 1975: PDP-11/34
- 1975: PDP-11/70 - first design using cache memory
- 1975: LSI-11 - first LSI design (also PDP-11/03, PDT150)
- 1977: PDP-11/60
- 1979: LSI-11/23 (F11)- second LSI design, first with floating point (also PDP-11/23, PDP-11/24, Pro 350)
- 1981: PDP-11/44 - last TTL design
- 1983: LSI-11/73 (J-11) - first CMOS design, last design (also PDP-11/53, PDP-11/73, PDP-11/74, PDP-11/83, PDP-11/84, PDP-11/93, PDP-11/94, Pro 380)
