Follow Sudoku rules, except that the digits 0-8 in trinary (00, 01, 02, 10, 11, 12, 20, 21, 22) will be used instead of the numbers 1-9. Givens may be the first, second or both digits of the final number. When only one digit is given, it should be clear which digit (the first or second) is the one given.

Sorry for the 0 in R6C8. It's a bubble of champagne that got away.
