Indeed, observing a system back then invariably required this or that level of cooperation from the target system itself, which automatically implies a change of its state was required - there was just no other way around. However, I am not so sure it is still the case nowadays. Introduction of hardware support for virtualization opens quite a few interesting possibilities for monitoring/debugging the system - after all, the guest OS is not even supposed to know that it runs within a hypervisor …
