MCA BUS
The MCA Bus
IBM’s Microchannel Architecture Bus possess the same types of signals ans accomplishes the same functions as the EISA, but the 2 are completely incompatible. MCA boards are smaller and use different edge connectors.
The MCA bus is designed to work with peripheral boards that transfer data in 8-bit, 16-bit or 32-bit words. For 16-bit peripheral boards, an additional 12-pin connector is used. One of the 16-bit slots also has a 20-pin video extension connector. This slot can be used for graphics cards.
For 32-bit slots also has an 8-pin matched memory extension connector.
