Here's the landing page for the book's implementation: http://www.cs.bc.edu/~sciore/simpledb/intro.html
Unfortunately, I don't think the book is in print anymore.
He even sells a kit with all parts and schematics included. It's easily one of my favorite projects of all time and has inspired me to continue learning more.
It's not close to MyCPU's level of complexity but is great to get you started.
