   corresponds to chip locations 13 12 11 10 9 8 7 6. I pulled two other //e out   
   of storage and they had bad ram also. Also this machine has no beep at startup   
   but the speaker does    
   click when.if i can get into monitor and sta c030 sta c030. Help?   
      
   I swapped RAM chips around.  The screen remains the same.  same lowercase p   
   and q -s.  Is it a MMU problem?  Zip chip problem?
