(munch) 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
