The decline of the minis happened due to the lower cost of microprocessor-based hardware, the emergence of inexpensive and easily deployable local area network systems, the emergence of the 68020, 80286 and the 80386 microprocessors, and the desire of end-users to be less reliant on inflexible minicomputer manufacturers and IT departments or "data centers". The result was that minicomputers and computer terminals were replaced by networked workstations, file servers and PCs in some installations, beginning in the latter half of the 1980s.
