Building Your Own Digital Device?

Skaven04 asks: "After finishing up my Digital Design class this semester I've suddenly got the urge to build something really cool. I'm leaning toward a processor/pda/calculator thingamajig. Not really a processor, considering that it wouldn't be following any set standards, like x86, but basically a machine that I can program with my own assembly language, have keyboard input, and (most likely) an LCD output (like on your TI85 or whatever). What I'm seeing in my head right now is an 8-bit design with an ALU (like the 74LS181) as the centerpiece and naturally a few 64K RAMs and various registers, counters, etc. as necessary to implement my command set. Has anybody else out there ever undertaken this kind of project? What are some sites I could visit to get a good outline of the best way to approach it? What are some good places to get the parts cheap? Any suggestions on displays? Links to similar projects?"

Best place to get parts?

Radio Shack! Duh!

As far as figuring out what you want to build... you've got questions they have answers.
