Emax

Hi, 

FIrst ever post on a Yahoo group so sorry if this has been answered.

Just bought an Emax 2 and am literally hooked. .
So, now that I have found love in my life of course I want to do everything I can to restore.  

First thing that needs doing is the screen.  I can read the writing on it but the blue background seems faded.  Its actually easier to see with the light on.  Any remedies?

Id like to uprate the RAM too.  I have done a little research into this and understand this is awkward to do.  I have 4 meg in mine so have the necessary daughter board.  
Is there anywhere I can get another 4 meg to max it out?

Also how easy are spares to come by?  I worry in the coming decade these these may not be maintainable.
