   Just a  bit more info.   
      
   If you remove an XRX-III, I think theres a single cut that you would need to   
   put   
   back.   
      
   And the 'DIN' connector in the photo.  That was for the second generation of   
   the   
   buffered EI cable mod.  It's a 6-pin DIN cable that went between the main   
   CPU   
   and the early EI boards.  Originally the buffered EI cable just buffered the   
   signals   
   and ran RAS, MUX, and CAS across the main cable to the EI.  However that   
   proved to not solve the reboot/lockup problem on all machines.  The later   
   fix was   
   to still use the buffered EI cable, but now the three mentioned signals were   
   taken   
   from the CPU board through 3 'twisted wire pairs' through the 6-pin DIN   
   connector to resistor terminations on the EI.   
      
   The DIN cable connector in the photo is just another part, not something to   
   do   
   with the small XRX-III circuit boards.
