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.
