I am planning on purchasing a a IBM model M. I need it to work with a PS2/USB connector. The two keyboards that I can purchase are:
IBM 1394167 (5 wire RJ11 connector, 122 keys)

IBM 1394308 (RJ45 connector, apparently fits IBM 3476 or IBM 3477 terminals)

If one of these can work with a modern PC, what sort of connector do I need?
