Oriented with the four pin connector at top right: The four pins are: +5, Gnd, Turbo LED, NC The three pins are the turbo switch: Low, common, High. The bottom row of 28 is the tens digit, and the one above it the units. Optionally there may be another four for a hundreds "1" digit which you apparently don't have. Segments are a-g left to right, and each segment is controlled by four pins arranged in a 'T', alternately upside-down and right-side-up. a b c x xxx x xxx x xxx etc. (spread apart for clarity) The junction of the three "bars" goes to the segment, and the three end points are the power source: Looking at each "T" in its proper orientation: Jumper down the leg = always on. Jumper on the left bar = on with turbo Jumper on right bar = on with normal Segments are named the usual way, a-f clockwise with a on top, g in the centre. Clear as mud? Hope it helps; almost as much fun as figuring it out yourself... mike
