Emax

I have an emax 2 model 2213 that boots up to 1 meg but states that there is a memory issue.  The unit came with the 2meg memory expansion disk. Opening it up it does seem to have the memory daughter board.  Any reason that it may be only recognizing 1meg?  Is it possible the board was not installed properly? 

Thanks!

You may have lost the eeprom programming.
This is the "scrambled megs" condition that people talk about.
Emu used to offer a service to fix this, but my understanding is they no
longer do so.....

My understanding also is that the disk is a one-time use and once you lose
the eeprom setting, you would have to re-program the eeprom.

Regards,
Ted

There are a few possibilities for this.. as Ted mentions, the scrambled megs 
problem is one possibility

I have also had this condition when the board or chips become unseated 
slightly.. I managed to cure this by removing the memory daughterboard and 
slightly lifting and re-seating the memory chips and then securely re-fitting 
the board.

I have also seen this condition when the PSU output levels drop, particularly 
the 5v level. 
It may be worth getting a re-cap kit for the PSU

hope this helps



Simon
