> A few questions on the output of the RGBI port on the 128... > 1) This is TTL RGB, right? That would make the signalling levels 0/+5vdc? Yes, TTL, but that doesn't mean 0/+5V. +5V is the voltage requirement for the TTL logic chips, logical 1 is not so high (I vaguely remember a number of 2.4V). > 2) Since the signal is being displayed on what essentially amounts to a TV > with a different input, is it safe to assume that the output is interlaced > in the same manner? Not exactly. By default at least the output is non-interlaced 50/60Hz, but of course most televisions show that without problems. Also note that a very crude black/white composite-compatible signal is available in the C128 RGBI output. > 3) Are the HSYNC and VSYNC lines the same as a composite display (nothing > inverted or anything...just put on separate lines)? I think so. To be certain you could check the C128 schematics. -Pasi -- "What's wrong, Ambassador?
