Most machines back then had reasonable instruction sets. For one, they were 
designed to be programmed in assembler. For two, they had actual humans 
designing them, rather than humans giving specs to a CPU-compiler.

I still remember the instruction layout and register layout of the mainframe 
I used in the late 70s, because it made such sense.
