Double post, but focusing more on the real computer. Do you have access to a library? Sometimes they have computers people can use. You might be able to load a program to rip onto a USB stick and run it portably (that is, without installing it onto the computer.) Not ideal, but if it’s Windows I think Windows Media Player can rip CDs natively.
In that case, bring in the CDs and the MP3 player, rip the CDs, then load them all at the library. There might even be CDs at the library you can check out as well.
Just start your car. It’s cheaper
