Well, the B&W signal is (with an exeption of the
VerticalF/Lines ratio) the same for both - and since
the resulting horizontal frequency is (almost) the
same, most B&W monitors are able to display NTSC and
PAL (or better US and European B&W) with only minor
adjustment. A good buy here is an Apple /// screen.
Simple, ad still fairly available.
