4004 MICROPROCESSOR SCHEMATICS
Complete Artwork, Schematics, and Simulator - Intel 4004
After completing the verification work for the 4004 microprocessor, I yearned to simulate a complete microcomputer set (CPU, ROMs and RAMs) at the transistor level. In late December of 2008, Tim McNerney sent me scans of the Intel 4002 RAM mask proofs. This was directly usable for the simulator, but the schematics were not available in any form.
Intel Museum releases 4004 microprocessor schematics on
Intel is celebrating the 35th anniversary of the Intel 4004, their very first microprocessor, in a way they've never done before, by releasing the chip's schematics, maskworks, and users manual to the public for non-commercial use. This historic revelation was championed by Tim McNerney, who designed the Intel Museum's newest interactive exhibit.[PDF]

Insanity 4004: Schematics
Since I already have schematics of the 4004, I guess I could have skipped right to the PCB layout. But having the schematic entered into a CAD package like CadSoft's Eagle allows electrical rule checks to be applied, verifying that the resulting board matches the schematic. I've been using Eagle for over a decade, so that was my first choice.

Intel 4004 - Wikipedia
The Intel 4004 is a 4-bit central processing unit (CPU) released by Intel Corporation in 1971. It was the first commercially produced microprocessor, and the first in a long line of Intel CPUs. The chip design, implemented with the MOS silicon gate technology, started in April 1970, and was created by Federico Faggin who led the project from beginning to completion in 1971.
