CP/M variants

CP/M (Control Program for Microcomputers) is an early operating system that was widely used in the late 1970s and early 1980s for personal computers. Developed by Digital Research, CP/M became a standard platform for microcomputers, especially those based on the Intel 8080 and Zilog Z80 CPUs. Over time, various variants of CP/M were created to serve different hardware architectures and user needs.

CP/M-86 is an operating system developed by Digital Research, Inc. for the Intel 8086 and Intel 8088 microprocessors. Released in the early 1980s, it is an extension of the original CP/M (Control Program for Microcomputers) operating system, which was designed for 8-bit microprocessors.

DOS Plus is a disk operating system that is an enhanced version of MS-DOS (Microsoft Disk Operating System). Developed by a company known as Digital Research, DOS Plus was aimed at providing improved functionality and compatibility for users and developers. It was designed to support multitasking and included additional features that were not part of the standard MS-DOS.

FlexOS is an operating system developed by the company FlexOS, Inc. Originally designed for use in embedded systems, FlexOS is geared towards providing real-time performance and flexibility for various applications. The operating system is often used in telecommunications, automation, and other industrial applications where efficient resource management and reliability are crucial. FlexOS typically supports a variety of programming environments and interfaces, allowing developers to build and deploy applications that can run on various hardware platforms.

IMDOS typically refers to the "Integrated Management of Development and Operations System." However, there might be other specific meanings depending on the context in which it is used. In computing and information systems, it could be an abbreviation for various tools or systems.

MP/M stands for "Micro Processors/Multiprogramming," which was an early operating system developed by Digital Research for use with microcomputers in the late 1970s and early 1980s. It provided a way for multiple tasks to run concurrently on a microprocessor, utilizing the capabilities of the hardware for multitasking.

Multiuser DOS (also known as MDOS) is an operating system that allows multiple users to access and share resources on a single computer simultaneously. It is a modification of the original DOS (Disk Operating System) which was primarily designed for single-user environments. Multiuser DOS was developed to provide multi-user functionality, including support for multiple sessions, user accounts, and various user management functions.
