Target entity: Concurrent CP/M Context triple: [CP/M, influenced, Concurrent CP/M]
-
A.
CP/M
CP/M is an early microcomputer operating system widely used in the late 1970s and early 1980s, known for its influence on later systems like MS-DOS.
-
B.
CP/M-86
CP/M-86 is a 16-bit version of the CP/M operating system designed for Intel 8086/8088-based computers, serving as an early alternative to MS-DOS on machines like the IBM PC.
-
C.
Concurrent DOS
Concurrent DOS is a multiuser, multitasking operating system developed by Digital Research as an advanced successor to CP/M-86 for x86-based personal computers.
-
D.
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.
-
E.
Multics
Multics (Multiplexed Information and Computing Service) was an influential pioneering time-sharing operating system developed in the 1960s that introduced many concepts later adopted by modern operating systems, including Unix.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.

How these facts were elicited
The pipeline generated the facts above by prompting gpt-5.1 with this entity's name + description and the instruction below.
Instruction
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
Input
Subject: Concurrent CP/M Description of subject: Concurrent CP/M is a multiuser, multitasking variant of the CP/M operating system developed by Digital Research for microcomputers.
