That trace is supposed to be cut.  Mine was and so was my friend's.

 It's good to know that you in the process of actually doing this project. I am about to get started myself.
 
 Just curious what this "rework station" is. Is this something I could possibly find at Radio Shack?
 
 As I was reviewing step 2 in the "Retro Instructions" I opened up my Emax and discovered that the trace between 11 and 12 instead of 12-13 on IC2 has already been cut. 
 
 Do you think that this will create a problem for me? And is there a recommended way to rejoin the trace?
 
 I too am planning to add the SCSI port from the back instead of adding a hard drive.
 
 I will be tracking your project in hopes staying safe with this project. I don't do this type of stuff often but I believe that I can do this project will some good reference and guidance.
