PDP-11

Target entity: PDP-11
Context triple: [Unix, laterPlatform, PDP-11]

• A. PDP-7
  The PDP-7 was a 1960s DEC minicomputer whose relatively low cost and flexible design made it popular in research labs and notable as the machine on which the first version of Unix was developed.
• B. Honeywell 316 minicomputer
  The Honeywell 316 minicomputer was a small, 16-bit general-purpose computer from the late 1960s widely used in early networking and control applications.
• C. COSMAC ELF computer
  The COSMAC ELF computer is a simple, low-cost, build-it-yourself microcomputer from the late 1970s that became popular among hobbyists for learning and experimenting with early personal computing.
• D. Honeywell DDP-516 minicomputer
  The Honeywell DDP-516 minicomputer was a rugged, 16-bit computer from the 1960s widely used in real-time and military applications, notably serving as the hardware platform for the original ARPANET Interface Message Processors.
• E. IBM 700/7000 series
  The IBM 700/7000 series was a family of early large-scale mainframe computers from the 1950s and early 1960s that played a key role in scientific, engineering, and business computing before the advent of more standardized systems.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
