Well for me it was a matter of how much time it took. I spent enough time understanding the Central Processor with all the weird CDC-specific terms. I had to reread several times before I realized Increment instructions did load/store. Oh, and that "bootloader" was called "dead start".

The peripheral processors were indeed a 10-way SMT thing, which they called a barrel processor. Each thread had three registers but they operated in really strange ways, and I just didn't figure that out.

There were other details like bandwidth being tied to bank count, which I also didn't go into.

For sure. I remember thinking.... "But where are the instructions to load and store X registers?" -- Psych! There aren't any! Just jam an address into a A register. Take that you RISC fan-boys, can you get to less than zero instructions?
