I'll let Tony answer that if he wishes to...
One of the reasons the Symbolics CPU is so nice is that the physical
arrangement of parts reflects the CPU architecture...
BTW the 9100 calculator doesn't use any ICs: its all transistors!

I think the most beautiful processor I've
seen is CPU card of the
Symbolics 3645. The wiring and chip layout are really nice. One thing that
I may be mistaken, but it seems to me that Tony was most likely
talking about the beauty of the engineering of the actual circuitry,
how the CPU (not a board containing a microprocessor, but a board
filled with the circuitry that makes up a CPU from many different ICs
- a true CPU board) was designed, as opposed to the superficial aspect
of a circuit board's appearance.
