This is the "twisted" version, for converting an XEP1541 adaptor into an XMP1541 adaptor. You can achieve the same with a normal Commodore serial cable and an XE/M1541 adaptor.

Construction

You need the following parts to build this cable:

• Two solderable 6-pin male DIN plugs (Commodore serial plugs)

• A shielded 5-wire or unshielded 6-wire cable of, preferably, at most 2 meters

Step 1. Solder one end of the cable onto one DIN plug.

Step 2. Solder the other end of the cable onto the other DIN plug. You should have the following connections:

   DIN plug    
   DIN plug    

    1, SRQ     
    1, SRQ     

    2, GND     
    2, GND     

    3, ATN     
    3, ATN     

    4, CLK     
    4, CLK     

    5, DATA    
    6, RESET   

    6, RESET   
    5, DATA    

Note that the cable has pins 5 (DATA) and 6 (RESET) swapped at either end. This is the swapping in which the XM1541 multitask cable differs from the XE1541 extended cable and which makes your XEP1541 adaptor operate as if it were a genuine XMP1541 adaptor.
