I found the problem. Not the solution yet... 

Soon as I tie in the last MB of RAM, to take it up to 9MB is when it goes haywire. I'm thinking its running into ROM somehow. odd... As long as I stay at 8MB and under, it all works beautifully. 

Soon as I add the last MB, spectacular failures ;)

My original CPLD design is perfect. Just didnt like the last MB.
