Just a note to anybody planning to purchase an xbit for a 1.6 install - it is highly reccomended that you do not as there is very little support for you, and the chip is simply not a good choice for installation on a 1.6 xbox.

My personal reccomendation would be to invest in an Xecuter 2.6, or a Xenium Ice - both of which have alot more documentation regarding installations on a 1.6 xbox, aswell as far more active sections in the forums.
