   my problem:

   I want to upgrade my cube to 16 mb. So I bought 8 SIMM's 70 ns 511000 (1x9).  
   Unfortunately the NeXT ROM Monitor said Exception #2 and that was all. 

The SIMMS RAM chips shipped in your machine are 1X8 (i.e. non-parity
RAM).
You can not mix (1X8) with (1X9).
The 70ns should work, but your RAM needs to be non-parity if you are
going to use the RAM NeXT put in your cube.

Bon chance,
