One way of looking at it is that an ordinary "good" assembler programmer/debugger on S/360 could reasonably know not only what all the instructions did, but all or most of their opcodes. Not like memorizing digits of pi or some similar memory-only exercise, but of genuine usefulness in reading dumps. On current machines this would be both close to impossible, and largely useless.
