Today, I learned more about z/OS than I ever thought I'd know. Not more than I ever wanted to know mind you, but more than I ever thought I would. I learned to read system dumps. I listened to people who rattled off assembly opcodes in hex like they were something everybody should know. It was kind of scary.
Of course, when I programmed in assembly for the 6502 (Atari 400/800/etc, Apple II, and the Commodore 64 all used the 6502), I could do the same thing. But, that was a long time ago. And I've done a little serious assembly programming for the 68000 as well, but I don't know any of its opcodes by heart.
