Legacy computer hardware and ribbon cables

There are three adapters for older PCs. One has phone jack. Another is what looks like one with ports for audio. The last looks like an RCA port, but am unsure. The last one does have some signs of use, and some pins are bent. There are a total of five ribbon cables. Then one little adapter for one of the boards possibly. I was unable to test any of these, but the packaged one and the phone board look to be in working condition so do the ribbon cables. Please feel free to ask any questions!
