There are three ways to set the screen colors from CP/M: 1. Manually, any of the first 8 colors for text can be chosen by typing CTRL-0 thru CTRL-7 on the main keyboard. Any of the first 8 colors for background can be chosen by typing CTRL-0 thru CTRL-7 on the auxilliary keypad. The second set of 8 colors are not accessible this way. 2. The program "conf" (AKA config) can be used as follows: conf char=<character color code>,back=<character color code> where the color codes include all 0-15 for each. 3. Any CP/M program can change screen or text colors by outputting to the console the sequence <ESC><ESC><ESC><color-select-byte> where the color select byte uses the low bits for the color code and higher bits to specify background or character color. This, in effect, can be used by a program to display text in assorted colors on the screen. The exact interpretation of the color-select- byte is given in the CP/M section of the guide that comes with the 128. Hint: try yellow on black or green on black, perennial favorites. 80 columns on a TV set (unless it's an XBR) is going to be real squinty at best, but more contrast will definitely help.
