Emax

Well, yesterday I plugged in 32 ICs into my 4mb turbo emax waiting for the adjust features codes by Richard Bruyn (eprelectronics.com)

I knew I have to wait for this code because only with it the emax will recognize the 4 extra mb.
And what did happen?:

3145684 wtf?! 

shocked but happy in the same way:

"only" 6 mb ... why that?! ... I didn't entered any code or something like that.

Do you have an idea ?

I guess one of the ICs is broken. How can I find out which one it is?

Thank you very much in advance!
