TTL signal
A TTL (Transistor-transistor-logic) signal is a digital signal level for controlling the screen colors.
With TTL driving, the red, green and blue signals can only be switched on or off or provided with an
intensity signal. A TTL-driven monitor can thus display a maximum of 64 colors. Video standards
such as MDA, CGA and EGA are based on TTL level.
