这本，还有 Jim Sather 写的《Understanding the Apple II》，是我最喜欢的两本书。把我的 Apple 2 拆开来看看特别有意思（虽然是台兼容机，但主板跟原版 99% 一模一样），一边看一边脑补各个 IC 芯片在各司其职，……
This, and "Understanding the Apple II" by Jim Sather are two of my favorite books. It's a lot of fun to open up my Apple 2 (it's a clone but the motherboard is 99% identical), and imagine all the different ICs doing their specific tasks,…
…to the original hardware design and in many cases, you can directly translate Sather's logic diagrams to Verilog code. BTW, Sather's book has recently been reissued: https://www.callapple.org/books-3/understanding-the-apple-ii...

……不实用，而且并不是在每台 Apple II+ 上都能用。我没记错的话，外设卡给总线增加负载就会导致它失效，而且有些兼容机上也没法跑。Jim Sather 的《Understanding the Apple II》里对此有详尽的记录，讲了具体技术，甚至还给了范例。小时候读到之后我还拿它做了实验，但我总觉得压根没法实际用上，因为要想把它整合进真正的游戏里实在太别扭了……
…impractical and didn't work on every Apple II+. IIRC peripheral cards loading the bus could cause it not to function and for instance some clones also didn't work. It was fully documented in Jim Sather's Understanding the Apple II where it described the technique and even gave examples. After reading that as a kid I experimented with it but I never felt like I would use it because it was so awkward to incorporate into a real game…
供参考，虽然这本书算写得相当不错（不过离 Disk 磁盘那一节远点，我没记错的话它完全搞错了 Apple 编码的工作原理），但公认的是，Jim Sather 写的《Understanding the Apple II》绝对是这个领域最好的作品：https://archive.org/details/understanding_the_apple_ii
FWIW, while this is a reasonably good book (though stay away from the Disk section, IIRC it completely misunderstands the way the Apple encoding works), consensus is that "Understanding the Apple II", by Jim Sather, is the clearly best work on the subject: https://archive.org/details/understanding_the_apple_ii
《Apple II Reference Manual》看这个合适吗？还是说有专门讲 Apple II 的更好用，比如《What's Where in the Apple》或者《Understanding the Apple II》？
Is the Apple II Reference Manual good for that ? Or anything specific to the Apple II, like "What's Where in the Apple" or "Understanding the Apple II" ?

……还原了原始的硬件设计，而且很多时候，你甚至可以直接把 Sather 的逻辑图翻译成 Verilog 代码。顺便提一句，Sather 的书最近再版了：https://www.callapple.org/books-3/understanding-the-apple-ii...
