IBM wanted to permit interrupt sharing so they did, and actually the MCA bus had dozens to hundreds of technical advancements over ISA. At the time that MCA came out, there were MANY motherboard manufacturers that were wanting to implement it on their boards. Unfortunately, IBM got greedy and demanded very steep licensing fees. As a result, the rest of the industry came up with EISA which is technically poorer. Otherwise, today we would all be running MCA. > As much as I hate to say it, there is a version of Linux >that will run on MCA, if you can find it.
