Somewhat OT, but anyway...
One of my other interests (it has been for much longer than I've been
interested in computers) it horology -- clocks, etc.
One day I will make a mechanical clock from scratch, probably to my own
design. It will, I know, be a poor timekeeper. A $5 quartz clock will be
a lot better. But there is a certain joy in actually making it oneself.
Others certainly feel likewise, there are a number of people who make
mechanical clocks, there are plenty of books on the subject.
I feel the same way about desgining and making a processor. Do it for fun.
You are not going to make a faster Pentium at home. Period. You might well
make something with a strange architecture or instruction set. You _will_
learn a heck of a lot by doing it, though.
