Indeed as you say, the plug was the Amphenol 36 pin as used by Centronics, and became popularised as the 'Centronics interface' - http://en.wikipedia.org/wiki/Micro_ribbon. Apple never used this 36 pin version, but they did make use of the D-Sub types for mice and computer ends of SCSI chains. the 50-pin Amphenol connector was used at the device ends of SCSI chains, as SCSI-1 Cheers, James -- Using Opera's revolutionary email client: http://www.opera.com/mail/

Do they even exist? Have I just been making unreasonable assumptions?
