Thanks for all the info about the many different microprocessors.
I had suspected that the 32000 was microcoded (elegant but slow)
and the 6502 was hardwired (primitive but fast).  What about the
6809?  It seems to have been a very nice chip (for an 8 bit) but
never went very fast.  Is this a good indication it was microcoded?

Also, what about the early Intel stuff, say 8080, and 8085.  I'm
interested about early designs too.
