The usual sorts of methods:  slip rings and rotating transformers.  The
latter may not be entirely obvious:  the two halves of a transformer don't
*have* to be in mechanical contact, and with suitable design there can be
a small air gap and the two halves can rotate with respect to each other.

If it were being built with modern technology (remember how old much of
that hardware is), it would probably use optical transmission for data.
