[citation needed] [example needed] DEC wrote, regarding their PDP-5, that it was "the world’s first commercially produced minicomputer". [10] It meets most definitions of "mini" in terms of power and size, but was designed and built to be used as an instrumentation system in labs, not as a general-purpose computer. [ 11 ]
A superminicomputer (Interdata 7/32) preserved in a museum. A superminicomputer, colloquially supermini, is a high-end minicomputer. [1] The term is used to distinguish the emerging 32-bit architecture midrange computers introduced in the mid to late 1970s from the classical 16-bit systems that preceded them.
From Minicomputer: A minicomputer (colloquially, mini) is a class of multi-user computers that lies in the middle range of the computing spectrum, in between the largest multi-user systems (mainframe computers) and the smallest single-user systems (microcomputers or personal computers). The class at one time formed a distinct group with its own ...
HP 3000 Series III. The HP 3000 series [1] is a family of 16-bit and 32-bit minicomputers from Hewlett-Packard. [2] It was designed to be the first minicomputer with full support for time-sharing in the hardware and the operating system, features that had mostly been limited to mainframes, or retrofitted to existing systems like Digital's PDP-11, on which Unix was implemented.
This list of computer size categories attempts to list commonly used categories of computer by the physical size of the device and its chassis or case, in descending order of size. One generation's "supercomputer" is the next generation's "mainframe", and a "PDA" does not have the same set of functions as a "laptop", but the list still has ...

The appearance of even lower-priced scientific workstations (e.g., Dana Computer/Ardent Computer/Stellar Computer (the merger of these companies)) based on microprocessors with high performance floating point units (FPUs) during the 1990s (such as the MIPS R8000, IBM POWER2), and Weitek eroded the demand for this class of computer.
For example, instead of instructions such as load and store, the PDP–11 has a move instruction for which either operand (source and destination) can be memory or register. There are no specific input or output instructions; the PDP–11 uses memory-mapped I/O and so the same move instruction is used; orthogonality even enables moving data ...
