Warning Heresy follows :) DG alert!

I'm not the expert on microcoding versus writable control stores. I seem to
dimely remember that there was a whole section about microcoding in the 1981
book by Tracy Kidder "Soul of a new machine". Lots of microcode was used to
emulate "old" instructions from previous machines. Also to perform complex
series of instructions.
