they used to
come with wall warts and now come with tiny little
bricks with a mains-cord socket rather than mains prongs instead.
They appear to be switchers, which has good sides and bad sides....
You may find
those SMPSU blocks will work from either 115V or 230V
mains with [no] user adjustments. I assume the input connector on the SMPSU is either an
IEC plug or
one of those figure-of-8 connectors, or at least something stnadard.
Figure-of-8? I suspect you're probably talking about the same thing,
even though it doesn't quite look like most fonts' 8 to me. Here's a
reasonably close depiction of the socket on the mini-brick, if you've
got a PostScript implementation available:
