Nice article about the layouting of the 6502:

Hi André
Some people may have seen this when it came out in Jan 2011, under the title "The MOS 6502 and the Best Layout Guy in the World" but thanks for posting - I think it's good to have a record here, and maybe a discussion!

Hacker News did have a discussion at the time. That should be here, but may be found here or here if offline.

Cheers
Ed

Might be worth a note that there's an update to the article ("In January 2015, I received the following note via email from Harry Bawcom"):

Just an FYI.

Bill Mensch did not layout the 6502, I did, with the help of two others.

In truth we all worked as a team but Bill didn't draw a single line on the first version of the 6502. My initials were on the die.

I wasn't there for the later versions.

Interesting. There were two other circuit designers involved, one senior to Bill. They deserve credit, too.


It seems possible that Harry got written out of the story after he'd left. I wonder if his initials fit in the blank space of the die...
