At our last users group general meeting a local mac programmer hacked together an init that allowed the Mac II's video board output to go directly to a large screen (NTSC) TV. It was done in software!! I know since I helped him debug it in the first of the meeting. The output of graphics was ok but reading text was not very good at a distance. If there's a demand for this maybe I can talk him into posting it. When you use the init NO output will be seen on your mac screen only on the NTSC monitor. Which means you must boot from elsewhere to remove the init to use your mac monitor again. It would be nice if you could use both at the same time. *********************************************************** usual disclaimers--- Patrick Mead ogcvax!inteloa!omepd!patm ***********************************************************
