CHAMP 36 versus CHAMP 50

Is the full-size CHAMP/Centronics-style connector the 36-position or 50-position form?

Computer-generated illustration, not a photograph. — P209 · ConnectorCentronics / CHAMP 36-position connector

How they differ

Centronics / CHAMP 36-position connector Count positions and confirm the equipment/cable specification; avoid choosing by the colloquial “printer connector” name alone.
CHAMP 50-position connector Count 50 positions and compare the CHAMP shell/latch geometry; verify the equipment or cable part documentation before assigning a legacy bus.

Then askIs the full-size CHAMP/Centronics-style connector the 36-position or 50-position form?
