| | Micro Channel architecture - Wikipedia, the free encyclopedia |
 | | Micro Channel architecture (in practice almost always shortened to MCA) was a proprietary 16 or 32-bit parallel computer bus created by IBM in the 1980s for use on their new PS/2 computers. | | | Micro-Channel architecture was designed by IBM engineer, Chet Heath and first introduced on the PS/2 series of machines in 1987; it slowly spread to IBM's entire computer line. | | | MCA was primarily a 32-bit bus, but the system also supported a 16-bit mode designed to lower the cost of connectors and logic in Intel-based machines like the IBM PS/2. |

| | The IBM MCA bus was an up-grade to the original PCAT ISA bus and was not back-wards compatible. | | | The IBM Micro Channel Architecture [MCA] bus was released around 1987 operating on the Intel 286 processor, then later on the 386 series of processors within the IBM PS2 series of computers. | | | The MCA bus is obsolete and should not be used with new computer systems. |

| | The MCA bus was also a 32-bit based architecture, as opposed to ISA which was only 16-bit. | | | MCA allowed one-to-one card to card and multi-card to processor simultaneous transaction management which is a feature of the PCI-X bus format. | | | Busmastering capability, bus arbitration, and true plug-and-play BIOS management of hardware were all benefits to the MCA bus. |

| | Micro Channel Architecture - MCA |
| | MCA, or the Micro Channel bus, was a competition for ISA bus. | | | Complete information about the MCA bus and other computer bus standards can be found on our computer bus help page. | | | The MCA bus offered several additional features over the ISA such as a 32-bit bus (although there was also a 16-bit bus), automatically configure cards (similar to what Plug and Play is today), and bus mastering for greater efficiency. |

| | MicroChannel Architecture is IBM's answer to the failings of its older PC bus, which is now referred to as the ISA (Industry Standard Architecture) bus. | | | POS means that on a properly designed adapter for the MCA bus, all configuration can be done with software on a closed machine. | | | The MCA bus was a masterpiece, unifying the best bus technology from the mainframe design with the demands from the PC. |

| | Why MCA? |
| | The primary reason there has not been a perceived advantage to the Micro Channel so far, is that it was designed for a multitasking environment, and most end-users have utilized it in a single-tasking manner. | | | The AT architecture does not easily lend itself to bus mastering, because it was developed for the single-tasking environment. | | | The Micro Channel, on the other hand, CAN share interrupts (due to the Micro Channel Architecture's use of Level-Sensitive Interrupts, rather than the Edge-Triggered Interrupts used by the PC bus). |

| | MCA (Micro Channel Architecture) Definition |
| | Stands for "Micro Channel Architecture." It is an expansion bus created by IBM that was used in the company's PS/2 desktop computers. | | | The MCA standard was designed to take the place of the AT and ISA buses used in previous IBM PC/AT compatible computers. | | | While the MCA bus architecture was an improvement in both size and speed over AT and ISA, it was kept as a proprietary standard by IBM. |

| | Micro Channel offered huge advantages over the older bus used in the AT: It was faster, it simplified the process of configuring cards, and it improved the ability of two add-in boards to work simultaneously. | | | Moreover, IBM initially charged vendors significantly more money for a license to use the Micro Channel architecture than it had for the older AT design. | | | But Compaq, AST, and others that had followed IBM's lead in 8088- and later 286-based (AT-compatible) computers balked at the licensing fees and the lack of backward compatibility of the Micro Channel architecture. |
