Also, they represent the Blackstone Group, which is self-explanatory.
The very best documentation I've ever read --- and I suspect was written by engineers --- was the Perkins-Elmer OS 8/32 Processor Manual --- once this was read through and through (took me about 50 times) one completely grasped and understood the operating system at the hardware level/software level --- truly a beauteous proposition!
The next wonderful documentation was provided by Mark Minasi, on the private or commercial side, but I don't believe he is writing it anymore, but his books were top notch!
People to be avoided were technically ignorant types like Scott Mueller, who was simply a copyist, and would copy long lists of hardware parts (a great list compiler) but simply and obviously didn't understand hardware or computer sci.
But my experience --- and many others --- was that once outstanding inhouse documentation is written, the efftard bosses usually believe they can do without you!
Time to cut the crap --- CIA has never been formally audited (I suspect the same applies to the NSA, DIA and others) --- time to audit them and shut them down as they have nothing to do with national security and EVERYTHING to do with supporting the Fourth Reich.
