The MCA bus fiasco was hilarious. Basically, IBM decided it wanted to retake control of the PC and get everyone to abandon the clones, so they came up with the PS/2 and its proprietary MCA bus, and they really thought everyone would suddenly abandon the clones and their open architecture and buy proprietary IBM PS/2 machines that were incompatible with everything. They didn't seem to understand at all that now the cat was out of the bag, they couldn't put it back in. It'd be interesting to see an interview of the idiot executives that hatched up that doomed scheme.
