Speak for yourself. I don't know about the VAX, but writing microcode for the Perkin-Elmer 3220 was fun and useful as well. It was nicely integerated into Unix, so different processes could have their own bits of microcode swapped into the control store when they were dispatched. Real Programmers weren't afraid of going down to the bare metal in those days.
