The SCSI specification describes a nonshielded connector in Section 4.3.
This is a typical ribbon-cable connector.

Appendix D describes alternatives for shielded connectors.  The
Alternative 1 connector is a shielded "ribbon cable connector", and the
Alternative 2 connector is what you describe as the "Centronics looking
connector".  Bob abbreviated "Alternative 2" as "ALT2".
