This site is the result of a great deal of assembly code reading, research, countless (mostly futile) searches for data sheets, cross-referencing and analysing. If you use this information in any way please mention wumpus <blacksphere@goliath.darktech.org> (and others in the credits section) in the credits of your program/document. And tell me :) If you have more information please contribute. If you just copy this, stick your name on it and call it yours I hope you get your genitals bitten off by a three headed monkey. Have a nice day.
No mobile phones were harmed in the production of this site.
