There are mistakes in http://nesdev.com/NESTechFAQ.htm
Now this document is from 2002, and is really old. But still, I think it needs revision.

Mistakes I noticed on one reading:
* DW4's size is 512k, not the 1024k overdump
* Miracle MIDI Keyboard does not plug into the NES's expansion port, it plugs into controller port #1.
