aha i see,

all i need is 1 nor, 1 nand, 1 sr latch, 2 xor, and a 1 bit tri state
buffer, I could probably do it with a very fast LUT too but im not sure if u
can feedback data lines to address lines reliably unless its clocked,
otherwise thats a few diferent packages even if i try and convert some of
the gates etc.

A gal16v8z doesnt seem to consume much power unless they are hiding it well
in the data ***, oh wait thats in standby, at 10mhz its 55ma but im not
pumping the clock line so maybe itl be a lot lower.
