Question Help with connecting Lasonic L-30 to a PC

[Munez1]

Hello there, I am very much a newbie to all the audio stuff. So here is the thing, I have an old Lasonic L-30 with 2 working speakers, I was wondering how can i connect it to my PC so I can use this stereo system as speakers for my PC?

Here are the pictures of the rear panel so you can see what ports it has:

As you can see there are left and right speaker ports, and also 2 PHONO ports in the middle. I was wondering what cable do i need to connect this device to my PC's 3.5mm audio jack? Thank you!

PS It wouldnt allow me to upload an image so i had to provide you with a link to imgur.

You're going to have to provide a larger image than that. i can't see anything apart from dark silhouettes.
Is this what it looks like at the back?

Like for like? Are you sure those Phono ports are for input and not output?

Yes this is exactly what it looks like, i mean the pic you posted! Well to be honest I dont even know the difference between input and output ports, I want to know can i use any of those to connect this reciever to my PC via some kind of Cable or adapter?
