RE: Good books in computer science?

Because it reminds me of when things went badly wrong. IBM360, Von Neumann architecture, no hardware stacks ... IMHO Burroughs and ICL had better approaches to OS design back then but had less resources to develop their ideas. However, mainly this period marked a transition from the excitement
