Emax

hi, anyone have an emax II memory upgrade daughterboard for sale or 
trade? or know where to get one? 
I have an old emax II that could possibly work as a 2 meg machine 
that I could trade. I tried to install its 2meg daughterboard into 
another machine, with e-mu's help. I couldnt get it to work and the 
guy told me the daughterboard was propably not functioning, I believe 
there is a problem with (Dram or Pram?)-according to the shop where I 
took it to get fixed. anyway at least it would be good for parts if 
nothing else. 
any info would be helpful. 
thanks, Antony West
