I love the part on modern systems where you put the Agilent or Tektronix logic analyzer on the frontside bus of your Pentium system and just after it triggers on your test condition it pops up the screen "Please enter your Intel NDA license in order to display signals" Seriously, a piece of test equipment that won't display signals for the device under test.
So yes, 30 years from now, I doubt you'll be able to look at anything useful on a modern system.
Intel licensed the protocol specs to Tek and Agilent so they could implement it in their logic analyzer, but mandated that it be behind an NDA-wall so people couldn't use an analyzer to easily reverse their bus protocols. The NDA nonsense started in the P-II days, during a time when both AMD and Cyrix were making drop-in chips for Socket-7, and Intel wanted to lock them out.
