You can find the details on how to build this cable at the construction page.


The assembled cable looks like this: complete cable, parallel plug at PC end, user port plug at Commodore end.

These pictures should give you an overall idea on how the cable looks like and how it should be properly assembled. However, when building a cable yourself, you should not rely on the pictures only; see the construction guide instead.


Switch your Commodore machine off. Connect the user port plug onto the user port of your Commodore machine, being very careful not to do it upside down, otherwise you may kill your PC parallel port within a second. Connect the parallel plug into the parallel port of your PC. Switch your Commodore machine back on.

Important! Do not plug or unplug cables while your equipment is switched on. Make sure that all components of your equipment are connected to the same, properly grounded power outlet. Put your equipment far away from monitors, TV sets and other devices with strong emission, otherwise cables may pick up interference and you may experience data loss or corruption.
