For some strange reason that is the same as an arrangement i used some
years ago for running a seven segment device.
I arranged for all the segments to be on normally.
When a single high occurred, it would extinguish some segments
accordingly, to make the appropriate display.
I did that with some diodes to the segments, so zero had one diode
over to the middle segment driver.
Two had a couple of diodes, top left and bottom right drivers.
Interesting that you should mention the eight, that had no diodes,
cos for an eight all the segments are lit.
