摘要
通过学习并口和模型机的知识,简要说明了并口模型机的概念与技术并对其分析,引出打印机并口的相关知识,阐述打印机并口的输入输出。学习实验中所使用的硬件,如74LS00、74LS244、平拨型D IP开关、电阻、实验板等。
By learning knowledge of parallel interface and trainer the paper explains the concept and technology of a parallel interface computer trainer and analyzes it to lead to relative knowledge of parallel printer interface. The input and output of the printer interface is expounded to learn hardware to be used in experiments ,such as 74LS00,74LS244,parallel stir DZP switch,resistance and test board etc.
