    • Characters are displayed on the screen of a cathode ray tube. The cathode ray tube electron beam is deflected in a trace representing the character to be displayed by sequentially applying various waveforms to the cathode ray tube deflection circuit. Digital control circuitry including a read only memory having segment deflection commands for each character to be displayed, shift registers set by the deflection commands, and AND gates enabled by the shift registers control the sequential application of the various waveforms to the deflection circuit. An additional shift register set by the deflection commands of the read only memory, a single shot multivibrator, and an associated AND gate control the intensity of the electron beam during the trace.
    • 字符显示在阴极射线管的屏幕上。 通过向阴极射线管偏转电路依次施加各种波形,阴极射线管电子束以表示要显示的字符的轨迹偏转。 数字控制电路包括具有用于要显示的每个字符的段偏转命令的只读存储器,由偏转命令设置的移位寄存器以及由移位寄存器使能的与门控制各种波形到偏转电路的顺序应用。 通过只读存储器的偏转命令设置的附加移位寄存器,单次多谐振荡器和相关联的与门控制跟踪期间电子束的强度。
