The 9368 has proper hex decoding of the pseudo tetrades - but those days
it was almost impossible to locate, compared to the common 7447 types.
Eventually, I programmed 74188s for that purpose, after a short period
(as a pupil) where I made a diode matrix decoder based on a 74154 -
this soldered well on breadboards.
