I don't think that tri-state logic is used in ICs anymore (?). EDIT: http://vswww.kaist.ac.kr/ENGLISH/old_lecture/ee878-2002/lecture/SoC_22-OCNetwork-1113.pdf

It probably does not imply that the chip is indestructible through microcode though.

How do busses work without tri-state logic?

That paper is about a different concept only loosely related to what DavidBuchanan seems to be talking about. Selecting a register through a tri-state based bus demands a circuit with a O(1) critical path. Selecting a register through a logical selector demands a circuit with O(log n) critical path, and a large constant factor.
