论文部分内容阅读
本书是软件开发必备、硬件维修必备、微机提高班教材。书中收集的电路和资料极为丰富,它包括了自APPLEⅡ生产以来的所有机型。因此,这实际上是一本“APPLEⅡ电路分析大全”。本书几乎对于所有使用和维修APPLEⅡ微机的人员都有阅读价值;对于渴望从事APPLEⅡ机进一步开发的软硬件工程师,则更有指导、参考、启发和实用性。内容:1.讨论了APPLEⅡ所有型号的主板和键盘电路。2.除帮助读者一般性地学习微型机硬件之外,还对APPLEⅡ硬件部分作了详细的讨论。3.提供了大量而精确的电路图和波形图,因此,可供维修服务人员准确地加以引用.4.对菊形链、中断、直接存储器访问及就绪线等比较深入的内容作了详细的解释.5.为搞接口部分的读者提供了许多有价值的资料。6.对视频信号、存贮器芯片和6502微处理器及许多高级的概念作了讨论。
This book is an essential software development, essential hardware maintenance, computer class to improve textbooks. The circuit and data collected in the book is extremely rich, it includes all models since APPLE Ⅱ production. Therefore, this is actually a “APPLE Ⅱ circuit analysis Daquan.” This book almost has read value to all personnel that uses and repairs APPLE Ⅱ computer; Have more guidance, reference, enlightenment and practicality to the hardware and software engineer that yearning to further develop APPLE Ⅱ machine. Content: 1. Discussed APPLE Ⅱ all kinds of motherboard and keyboard circuit. In addition to helping readers learn the general micro-computer hardware, but also on the APPLE Ⅱ hardware part made a detailed discussion. 3. A large number of accurate circuit diagrams and waveforms are provided so that they can be accurately referenced by service personnel.4 More detailed explanations of daisy-chain, interrupt, direct memory access, and readiness lines are provided in detail .5. A lot of valuable information is provided to readers of the interface section. 6. Video signals, memory chips and 6502 microprocessors and many advanced concepts are discussed.
