Message text written by INTERNET:classiccmp@u.washington.edu call them 'Amphenol Connectors' in the UK (while realising that Amphenol make a wide range of different connectors). I've also seen them called 'Centronics Connectors' (after the common use for the 36 pin one I guess), IEEE (or IEEE-488) connectors (after the common use for the 24 pin one) and 'Telco Connectors'. I think the last is what HP call them.< They are generically called "Centronics connectors" in the U.S., being 36 pin, 24 pin, or whatever. The HP connectors are called IEEE-488, since that is the standard they follow; never heard them called "Telco connectors" by HP or anyone else. Gil Parrish
