- aargh.

- At the risk of beinb called pedantic, Centronics is an interface definition,
- (and a printer company), not a plug. The Plug is an Amphenol plug, 50 Pin
- in this case, where the Centronics interface uses a 36-pin Amphenol plug,
- and the HP-IB interfas a 24 pin one.
-
- It would not be so bad, but many people now take "Centronics plug" as referring
- to the 25 pin Cannon plug which is a printer connector on the IBM-PC/AT
- and ISA architecture and which Apple uses - you guessed it - for the SCSI
- connector. Get a few gender changers and a random selection of "Centronics
- cables" plug it all together and we are talking blue smoke!
-
- So get this into your fingers, everyone:
-
- plug (physical) interface (logical)
- 25 pin Cannon Serial Port
- " PC non-standard Centronics-type printer interface
- " Apple non-standard SCSI-type interface
- 36 pin Amphenol Centronics interface
- 50 pin Amphenol SCSI interface (or even "SCSI Port")
- 50 pin IDC on-board SCSI port connector
- 60 pin I5F6743 YAFST (yet another funny SCSI terminator)
