[net.micro.6809] Coco-II mod to Greyscale Monitor

The grey-scale monitor ckt I posted last month refers to
signal from the MC1372 chroma modulator chip.
This has been eliminated from the Coco II and absorbed into
the tin-box RF modulator itself.
(I just saw the new Coco-II tech manual--really slick).
Coco-II owners must tap off the
Luminance, phase-A, and phase-B
signals from the 6847 VDG chip,
pins 28, 11, and 10 respectively,
or where these go into the new modulator box.
Say, has anyone tried my circuit?  Anyone want a re-posting?  mike k
