Hi,
if you're interested, I offer to upgrade your Emax II. Please make sure that yours has this expansion board:

As I need the whole Emax to do it, shipping won't be cheap. I'm in western Germany.
I did it with mine as well. It was a hell of work to assemble all the information and parts, writing e-mails and blahblah...
Originally mine had only 4MB and now 8MB! It's definitely worth it and ... really cool
Contact me for further details.
