The two DB-9 black Joystick cables are connected up to the ST Joystick/Mouse ports and back to the Loopback green PCB (most ST computers require you to crisis cross (not one to one) these DB-9 shorting cables back to the loop back PCB to get the proper port diagnostic results).  The short black or gray DB-25 Parallel cable is connected to the ST printer port and loop backboard.  The short gray ST DB-19 DMA cable is connected to the ST DMA port and the loop backboard.  The 5 pin Din shorting cable is connected up to both ST Midi Ports (one end of this Midi cable has a Red LED molded into the translucent connector housing to see the Diagnostic Midi Send and Receive sent signals).  The DB-25 Serial port shorting connector is connected to the ST Modem / RS232 external Port.

Atari Tech Tip on the Loopback ST PCB board.  Our Atari Super Tech strongly recommends you tape the anti Static pink bubble bag the Loopback board comes in (or tape a piece of thick and oversized piece of cardboard) to the exposed back side / solder side of the Loopback PCB board, to prevent it from shorting out / damaging the different I.C.ís on the top side of Loop back PCB should the back side of the exposed PCB come in contact with any metal.
