Hello. I'm somewhat new here.

I decided about 2 years ago that it would be really cool to make a working computer from scratch. Unfortunately, It has remained a dream due to my lack of time/knowlege/money.

However, my electronics teacher loaned me a cool book today titled: "Practical Digital Design Using IC's" (second edition) It is very informative and I have already ordered my own copy. The book has re-kindled my plans to make a computer.

I am looking for an easy first project. My criteria/goals are as follows:

1. some sort of text based interface. I may be able to find a dumb terminal to use. If not, I still need a keyboard/screen somehow. (TV set?)
2. programmable (Machine, assembly, basic, I don't care.)
3.It would be nice if it could save the programs created on it.
4. Emphasis on easy.

I would like to build it around some sort of microprocessor like the 6502.

Side Note: This project was partly inspired by watching "The Pirates of Silicon Valley"

Anybody have any ideas for me? I found a few, but they need a serial interface to a real PC to serve as a terminal and save programs, or they are not easy.

I really liked this one:

I'm just looking for more options (Easier, mostly but more functionality would be nice.)

Okay, last thing: where do I get the parts for the zx80 mentioned above?
