MCA

MCA stands for Micro Channel Architecture and is supposed to be the successor of ISA. MCA possessed a 32-bit wide transfer bus and was self-configuring. The problems with MCA were that the MCA slot was not compatible with ISA cards, but what actually made MCA an unattractive technology was when IBM released MCA in 1986, they did not release it to the public domain and charged a fee for each MCA slot included on a motherboard making MCA very expensive. Those of you old enough to remember Sony BETA video recorders will recall that the same issue ended BETA technology, allowing VHS video recorders to take control of the market.
