I think it is nice to have the 7-seg to go
0 1 2 3 4 5 6 7 8 9 A b C d E F
to get full hex readings on the output.

Add some additional logic to the schematic from EM Fields...

With no optimization:

Oops... "7" is missing SEGF. I'll fix it when I get a chance.

Drawings fixed; see post #10.

 

It is always a good exercise in keeping a schematic neat and orderly! Especially for the beginner who almost never manage one that is this easy to read until their second or third try.

In addition to 7, you seem to have the wrong number of segments on in 4, 8, b, E, and F. Also seem to have the segments mislabeled; 'a' is on top, as shown in post #2.

 

Is our Thread Starter still around to benefit from the corrections?

Yup, good catch, thanks.
Here are the corrected drawings:

According to his Profile, not since the first post. Good info for others, though.

There were no corrections made by dl324, so any benefit accrued isn't from corrections made, it's from the errors he pointed out.
