"Back in the 80s, the Commodore C-64 had an intelligent floppy drive, the 1541, i.e. an external unit that had its own CPU and everything. The C-64 would send commands to the drive which in turn would then execute them on its own, reading files, and such, then send the data to the C-64, all over a propriatory serial cable. The manual for the 1541 mentioned, besides the commands for reading and writing files, that one would read and write to its internal memory space. Even more exciting was that one could download 6502 code into the drive's memory and have it executed there. This got me hooked and I wanted to play with that - execute code on the drive. Of course, there was no documention on what code could be executed there, and which functions it could use." Very interesting. I'm most interested in how he describes others taking his work, and making it better. This would be impossible today, thanks to Microsoft, Apple, and other patent trolls.

“上世纪八十年代，‘准将 64’PC（the Commodore C-64）拥有一个智能的软驱——1541。1541，打比方说吧，就是一个拥有自己CPU以及其他一切的外部单元。准将64向该软驱发送命令，它会将它 们在本地执行，进行读文件等操作，然后通过一条专有串行总线，将数据发送给准将64。1541的手册上提到，人们不光可以向它下达读写文件的命令，它还可 以读写它内部的存储器。更加令人兴奋的是，人们可以下载6502代码至其存储器，让它执行它们。这深深吸引住了我；我好想试试在软驱上执行代码。当然，那 时并没有关于什么代码可以在上面执行，什么函数可以使用等的文档。” 整个故事非常有趣！特别是作者讲述的其他人是如何继续他的工作，使其变得更好的故事。今天，这已经不可能了。不可能了。感谢微软，感谢苹果，感谢其他的专利恶魔！
