MCA

By 1987 IBM was getting a bit annoyed. Here 'the real computer company' was getting its clock cleaned by companies like Compaq, PC Limited (now Dell), Heathkit/Zenith, along with hundreds of 'garage shops' that were purchasing 'white box' parts and assembling computers with better performance at a lower cost. IBM’s market share was dismal, and getting worse. IBM, like Ford, thought they had a better idea.

That better idea was the PS/2 computer series, with all but the lowest end model featuring a new expansion bus known as Micro Channel Architecture (MCA). As we saw in Chapter 0000, IBM was going to let everybody have MCA, for a price. Now while everybody agreed that MCA was a superior alternative to ISA, just about nobody was going to pay that kind of money ($1 per slot, per system board!). Not even for 32-bit performance.
