4004 @ 44: SVG Mask Artwork; New Busicom 141-PF replica PCB; Printer emulator
Tim McNerney's original goal for starting this project was to make the invisible machinery of the first computers-on-a-chip visible and understandable to students and the lay public. The 4004 is great for many reasons, but for this project it's number one selling point is that it is a minimal CPU. This is extremely useful for teaching purposes. In the coming months before the 45th anniversary, we will be working to make the 4004 and fundamentals of computers and digital logic even more accessible though the confluence of art, education, and technology. This project could never have been done alone. It needed an international team of volunteers.

Programming on Early Microcomputers: A Retrospective
That is the context of the early machines: computers that blazed a path (which I think was not clear at the time even to their creators) for how people could use small machines, which we ever-so-preciously called microcomputers (compared to minicomputers such as the DEC VAX, which were all the rage in geek circles). These were the experiments that lead to the mainstream forms of personal computing that followed.

Elliott 803 Simulation - ALGOL
> The Elliott 803 had an excellent compiler for the then new ALGOL 60 programming language. ALGOL 60 was pretty much the first "block structured" language and was hugely influential on just about everything that has come since. For more information on ALGOL 60 itself try Wikipedia http://en.wikipedia.org/wiki/ALGOL.

homebrew-6502 primer: intro, reasons
So you've decided to build a 6502 computer-- or maybe you're still deciding.  You've been looking at the 6502 instruction set and some other materials on it.  Go ahead and build.  You'll enjoy it and learn a lot.  My own first creation (in 1985), although it worked, was a lot of work to make and was not very useful, but it was the beginning of learning what would be easier and more useful.  This set of articles will give you helps and shortcuts I didn't have back then.

Ken Shirriff's blog: (A small part of) The 6502 chip explained down to the silicon
The circuit above shows the actual implementation of the overflow circuit in the 6502 using NMOS transistors. The circuit to generate the overflow flag is very simple, requiring just a few transistors to implement the three gates. A, B, and carry are the inputs, and the output #overflow indicates complement of the overflow signal.
