…成排成排的科幻小说，根本没有我如今买的那些冷门专业资料。你是什么时候开始买书的？我当时住在一个小镇上（大概 4 万人），1981 年的时候，我订购 Lance A. Leventhal 的《6809 Assembly Language Programming》，不到一周就能拿到手。6502 版本的甚至有现货。问题在于，当时连锁书店差不多就在当地商场冒头了（我们当地是 Waldenbooks），然后把…干掉了
…shelves of science fiction, and none of the strange specialist material I buy today When did you start buying? I lived in a small town (roughly 40,000 people) and in 1981 I could buy Lance A. Leventhal's "6809 Assembly Language Programming" on order in less than a week. The 6502 version was in stock. The problem is that chain bookstores emerged right around this point in the local malls (Waldenbooks, for my local area) and killed the…
等等，什么鬼？William Barden 的《TRS-80 Color Computer Assembly Language Programming》绝对讲了外设啊。就连 Lance Leventhal 的《6809 Assembly Language Programming》也涵盖了 6820 PIA。最大的问题其实是，严格来说 Lance Leventhal 的书跟 EDTASM 汇编语言磁盘和卡带并不兼容。这坑得我焦头烂额，直到…
Wait, what? William Barden's "TRS-80 Color Computer Assembly Language Programming" most certainly did cover the peripherals. Even Lance Leventhal's "6809 Assembly Language Programming" covered the 6820 PIA. The big problem was that Lance Leventhal's book wasn't strictly speaking compatible with the EDTASM assembly language disks and cartridges. That caused a lot of grief for me until…
…had all but forgotten. The first ever assembly language program I got to run was a bubble sort implementation that sorted the text characters on the screen. I painstakingly typed it in from a book on 6809 assembly language programming. I didn't know what it was going to do, so I was blown away when I saw how it could actually manipulate and sort characters in video memory right before my eyes.

…早就忘得差不多了。我跑通的第一个汇编语言程序是一个冒泡排序的实现，用来给屏幕上的文本字符排序。我是从一本讲 6809 汇编语言编程的书上一字一句敲进去的。我当时甚至不知道它到底是干嘛的，所以亲眼看到它竟然能直接操作并排序显存（video memory）里的字符时，我整个人都被震撼到了。
