This compilation details computer models utilizing the Micro Channel architecture produced by IBM. Computers created by other manufacturers following this architecture were often referred to as PS/2 clones or MCA clones. The inaugural third-party Micro Channel system was the Tandy Corporation 5000 MC, debuting in July 1988. Although substantial investments were made in research and development—including expensive IBM licensing costs—by 1990, the majority of MCA clones did not achieve complete compatibility with the Micro Channel architecture or its expansion cards. As IBM gradually discontinued the PS/2 series, which had introduced Micro Channel in 1987, by 1992 only a few companies like NCR Corporation continued producing MCA clone systems.
