Faulty Calculator Puzzle

Genre: Logic Rating: 5 - Medium Source: William Armstrong
Brain Functions: Analysis / Visualization Hint    Solution

A simple digital calculator uses seven segments to display each digit. When all seven segments are "on", the digit displayed is 8. When only the two segments on the right are "on", a 1 is displayed. The illustration shows each digit 0 through 9 exactly once. The problem is that many of the segments are broken. When the broken segments are turned on, they don't darken the way they are supposed to. Your puzzle is to identify all ten digits.

Here is what the ten digits look like when the display is working properly. Of course, the puzzle displays the digits in a different sequence.
