 From the HP-97S user manual (I have one on loan
for a demonstration in a   few weeks...)

 'Your peripheral device is connected to the HP-97S interface with a 
 standard 25-pair telephone connector (Amphenol 57-30500 or equivalent)' 
Ah.  Yes, we used to call the 50-pin version a telephone or telco
connector because, well, that's where we used to find most of them:
going to a 5-line office phone, or on the side of a punch-block.

But HP-IB and Centronics printer connectors didn't have enough pins to
be called telco connectors.  Besides, HP-IB used bigger, stackable
screws, and Centronics printer connectors had those ears.  It wasn't 
'til I saw the 50-pin Centronicsish SCSI connector that I started to
get confused.
