The user could "switch in" four lines of text in the Hi-Res mode, just like in Lo-Res mode; however, this hid the bottom 32 lines, resulting in a 280x160 picture. . The Apple II video output is really a monochrome display based upon the bit patterns in the video memory (or pixels). The colors were created by filling the pixel with a repeating 4-bit binary pattern in such a manner that each bit group fit within one cycle of the colorburst reference signal.

Assembly Lines video podcast #17Make a splitter cable that goes from the Apple //e composite output to the LCD composite and S-Video inputs.It's a custom cable. They convert from composite to VGA very differently. The main differences between a hi-fi cable and one intended to carry video signals are 1) the video cable usually has a better, tighter shield; 2) the video cable is characterized for impedance matching at, usually, 50 or 75 Ohms; and 3) the video cable exhibits lower capacitance between the center lead and the shield. In the IIGS it was an output for an analog RGB monitor specially designed for the IIGS. Right side view. The Apple II was the only one to support color graphics and connect to a TV using an inexpensive RF modulator, making it possible to avoid the cost of a monitor or use an inexpensive 9″ security monitor with composite video input. I was going to hack the color killer not to work thinking it may have . The Lo-Res graphics mode offered built-in commands to clear the screen, change the drawing color, plot individual pixels, plot horizontal lines, and plot vertical lines. This improves the readability somewhat but on screens with combined graphics + text you get the same problem. The odds of getting one that works is just too low to justify even the small price.
