How do I make JavaScript "pop-up help" accessible?

Dear Group,
I site I am reviewing generates context-sensitive "pop-up" help using
JavaScript.  I imagine they are doing this for the effect that:
(1) The main window stays open;
(2) The new pop-up window is smaller than full-screen and has none of the
normal browsing controls -- so it doesn't really look so much a web page.

The pop-up is invoked by code like:
<A href="JavaScript:Help('foobar.htm')">definition of FooBar</A>

Obviously, the HTML file is available if one can figure out how to hunt it
down (it's fairly well hidden).  Lynx just generates a message:  "Alert!:
Unsupported URL scheme!" and nothing happens.

Is there an alternative way to code this so that 4x browsers still get the
no-frills pop-up version, but Lynx (and other JavaScript-free) users get the
regular URL for the help text?

I need help with this kind of urgently.  If the techniques document goes
into this much detail, please feel free to slap my wrist after referring me
to the right section!
