1983 年那会儿，我需要用汇编给 Apple II 写屏幕寻址例程。我去了谢菲尔德当地的一家书店，买了 Marvin L. De Jong 写的《Apple II Assembly Language》。这是我本科毕业设计的项目，多亏了那本神书，我才顺顺利利拿到了学位。
I needed to write screen addressing routines in assembler for the Apple II in 1983. I went to my local bookshop in Sheffield and bought "Apple II Assembly Language by Marvin L. De Jong". This was for my undergrad project and I pretty much have a degree because of that awesome book.
