Earlier in chapter 9 it says he uses an Amiga but then later he is not allowed to keep his now ancient "Apple" computer? Typo or did he have both? Typo methinks. After all, there are only PC and Apple computers right?
And I didn't read it yet (if it is detailed in the book), but what computer did the australian hackers use to hack NASA? Was it a C64 or was it an A1000?
