The connector on the back of the 8620A is a 18 pair connector that is the
same as the one used on the centronics printer cable.
The connector on the back of the 8620C is a 25 pair connector that is the
same as was used by the telephone company on multi line desk sets. It is
also used on very old scsi systems.
HP made an adapter between the 50 pin 8620C connector and the HPIB
connector for use with the HPIP option.
Note that all of these connectors are micro ribbon connectors.

I am looking to do some interfacing to the 50-pin connector on the back of a
(non-GPIB-compatible) HP 8620C. This looks very much like an old-school
SCSI connector, but unfortunately I've long since tossed all my old SCSI
cables.
Can anyone do me a huge favor of confirming/disputing this observation?
Could save a few bucks.
Thanks! -- john KE5FX
