Robert Dukelow (a fellow netter) just told me about a product for this.
Neither of us has tried it.  Its been on the market since 1981, and is the
only product of a small company.  The people there I talked to by phone
seemed pretty smart.  Its called "The Grayscaler".  An ad reads:

  "Create crisp composite video directly from your color graphics card RGB
  port and enjoy sixteen shades of brightness.  Ordinary monitors come
  alive with complete RGB equivalent software compatibility for the IBM
  PC, XT, AT, Compaq, Columbia, and other compatibles and color cards.

  "Miniturization packs a high speed D/A, synch circuit, and line driver
  in a single cubic inch module.  External installation on RGB connector
  does not use slot.  Phone jack output.  Interference-causing color is
  completely sidestepped by Grayscale."

On the phone they said you needed a COMPOSITE (analog) monitor, and it would
not work with a "TTL" monitor (e.g. IBM Monochrome, Amdek 310A).
