Computer speakers (Southport PR9)

These date from the 1990s. They are designed to be powered from the same power cord as the computer. That is, to be sandwiched between the power cord and the computer. The is a separate plug for the computer audio output. Power and audio leads are both 46 inches each. The speakers can extend 39 inches apart. I also have the black power cable with plug. This is approximately 100 inches long.
