On a lighter note i had some one tell me to day that the reason why the dmd display is only half working at any one time on the machine they are selling is because the batteries on the CPU board need replacing. 
thank heavens for that, i thought i would have to replace the display but it turns out i can save heaps of $$$ just by replacing 3 batteries. 
 

Yes, those batteries cause all sorts of stupid problems don't they...
