So you want to know why they have but in a choke in the C64? or did you figure that yourself?

Are you talking about RF Chokes?

FCC requires you to be able to accept RF without going wrong. When you
have wires coming into your computer then they act as antenaes and any
radio interference will cause interference inside your computer.

The other way around actually: the computer will radiate interference in nearby radios and TVs.

That's also the purpose of those ferrite beads that you see on all the I/O connectors in 128s, Amigas etc.
