for a start: http://www.homebrewcpu.com/

later on you could replace the logic-chips with discrete gates. ;)

in any case it takes some personal attachment to such a project! ;)

BTW, I'd be seriously interested in finding out what such a discrete recreation like the 741
does to circuit design which relies on the specific characteristics of the OpAmp, like distortion of a filter.
