Homebrew computer from logic gates etc.

I've been searching the threads throughout the day. I cannot find any
useful references to information about designing and building a
computer from logic gates, flip flops, etc. The information seems to
be scattered and incomplete. I have some experience with digital
electronics. I'm interested in learning a lot about the architecture
of computers while producing something slightly useful and if nothing
else amusing to watch (LED's). I have a book containing specific
information on many types of circuits that would be very useful in
building a computer from scratch, however, the information about
building a computer is limited.

If anyone could point me to some solid resources, I'd be very
appreciative.
