Yes, there is a way.  (In fact, when I got my Magnavox Computer Monitor 80,
this had to be done to get it to work.)

All you need to do is take the pin marked monochrome out of the 128 and the 
ground pin and hook them up to the composite video in port, ground on the
outside.  I have the pinouts back at my room; if you need them, just drop
me a note.
