Back in mid-2002 when I first picked up the 2600 hobby (my life has never been the same since!) I spent a couple of weeks buried in the TIA-1A schematics mentioned in the archives; I wanted to understand just what makes it all work the way it does.
At the time I scribbled heaps of notes all over loose sheets of paper, I still have a pile of them here somewhere :p I also started writing some of this info into a document, which has now reached a point where it might be useful to someone. I'm not sure that any of this isn't already common knowledge - z26 seems extremely accurate!
Anyway here it is. It's fairly technical in parts and discusses some things down at the gate level, but most of it is readable by normal humans (none of us, then ;) It's still a bit rough but I'll keep working on it if people are interested.
Please note that I have no formal background in NMOS chip construction, but I have some electronics background. There could well be some silly mistakes in this document.
If anyone needs a non-zipped version I can email it directly; it's about 46K.
