One can make a good }argument for also providing a better bus for crucial things, like fast }disks, but nobody is going to want to redesign *all* the interesting }peripherals, and nobody is going to match the production volumes (and }hence cost savings) of (say) AT peripherals. While I like the idea of an (almost) free computer, I don't think it is worth it. Considering that you can go out and buy an *88 board for under $ 100, and a 286 board for under $ 300, it isn't worth it to design and build your own (ok, just build). By the time you get done buying the chips, circuit board, and other misc. parts, you will have spent a lot more than that. On the other hand, if you are doing it for the _fun_ and the learning experience then it makes sense.
