They don't. The frequency won't matter, only having "about" the right
voltage. Actually, I once (when I worked for an Acorn distributor) came
across a guy working abroad who had inadvertantly used his unmodified Beeb
on a 120V supply and never noticed until he bought a monitor -- which
refused to work at such a low voltage. I wouldn't suggest you try it,
though; it should be easy to change the PSU setting.
Many monitors may not care too much about the frequency either, but it's
probably easier to get one that can be set to 110V; a CGA or Amiga monitor
should work. I'd strongly suggest an RGB (TTL level) monitor rather than a
PAL or other composite colour monitor, as the higher-res screen modes
aren't too sharp when the colour signal is added to a composite signal.

Don't try it. Neither the adapter nor the Beeb's switch-mode PSU will like
it.
