Two modes: Plotting and text. Write text from rom, uses a shift register to determine where to write the letters. Uses a plotting decoder to decode the X & Y values from the user input. The screen runs off t-flip-flops. Has a reset button, resets every time a mode is switched.
The GPU has two modes; Plotting and Text. With plotting you, indicate your X & Y by flicking the levers, corresponding with X & Y on the screen. When you want write it to the screen, press the button labeled write next to the levers. The screen works by inverting the screens current state. So if you want to un-write a pixel, just select its X & Y and press write. Press the reset button above the write button to reset the screen to blank. If in text mode, Press a button corresponding to the letter of your choice. Once four letters have been displayed, press a letter to reset the screen, if you wish to continue writing, Press another letter. Then any further letters will appear on the screen.
