Whats wrong with the old designs... Iv used them loads of times and they work amazing. Never had any problems
Well, I just didn't like them. Using just a Zener for the regulation of the 3.3V is not correct in my eyes as it can fluctuate if its not properly regulated. And I prefered using these threestate buffers as they will guarantee correct logic levels. Old versions probably work most of the time, but I prefer this.

Nice work! I take it you never found a way around the 5vstb problem with 1.6 psu's?
nope, we had a small discussion about it here:http://forums.xbox-scene.com/index.php?showtopic=548150
but I'm not sure anyone tried it out. Problem is the huge load on the 5vsb rail
