PDP's lack of naming really confuses things, they essentially just numbered the computers by release date.

There are like 3-5 completely different family trees of computers in their numbering scheme (depending on how you count), all of them are notable in some way.

Yeah, there were two busses, and the bigger ones were certainly rather impressive. I built a PDP-11/23 out of spare bits gifted from a university physics department in the late 80s, and it was awesome, but nothing like an 11/70 or anything like that!
