Indeed the documentation was a level that service engineers today would envy and more so techincal details at a level you only get from some serious reverse engineering/hacking today. Kinda best way to put it is documentation was akin to what you would expect from a mature MCU today as comparable level and in some ways, more accesable and you felt you owned the computer more and had a more intermate understanding. Though many things go that way, Cars another example and cars of that era, you could get documentation and fix yourself. Today, you under your hood might as well be a Borg cube.
