context_page_description: Micro Channel architecture, or the Micro Channel bus, was a proprietary 16- or 32-bit parallel computer bus introduced by IBM in 1987 which was used on PS/2 and other computers until the mid-1990s. Its name is commonly abbreviated as "MCA", although not by IBM. In IBM products, it superseded the ISA bus and was itself subsequently superseded by the PCI bus architecture.
context_section_description: The Micro Channel architecture was designed by engineer Chet Heath. A lot of the Micro Channel cards that were developed used the CHIPS P82C612 MCA interface controller; allowing MCA implementations to become a lot easier.
