Yes, I remember those dot-matrix condensed-font license numbers with ambiguous squiggles for zeroes, eights, threes, fives, sixes, and perhaps others. One comfort is that the letters don't go up to letter "Oh," so that's one fewer combination you'll need to try if your license is not registered. A real false economy, trying to make long numbers fit on short labels. I'm sure increased tech support calls just decoding the jumbles.
