Not too far out--really!

Not that long ago we had to build a functioning RISC computer from logic ICs at Cal Poly Pomona. And not as a part of an EE program either--it was a part of the CS curriculum!
In all the time I spent there, that was one of the most interesting things I've ever done. Luckily for us, we didn't have to design and etch the boards, but we did have to come up with the microcode and burn it into EPROMs as well as solder a bunch of components and IC sockets onto said board. We also had to write an assembler for it as well and of course the whole thing had to work if you wanted to pass the course!
It was only capable of handling 4 bits at a time and was manually clocked (keep flipping faster! I need those spreadsheet values by tomorrow!) but by God the thing actually worked. And you could actually understand how it worked.
Even though you could conceivably expand the thing to 32 or 64 bits, I can't imagine why anyone would. Except of course if you're living in a post-apocalyptic (or post NGSCB) world where you can't walk into a store and buy one...
