8-o
Whatever! Here's a shot of some of the external Centronics 50 hackage I've done . . .
. . . w/o doing any damage to my incisors/canines . . . :
. . . with an internal SCSI extension cable, and a split cable (for making tight turns & offsets) thrown in for good measure. The C-50 connector w/o the PCI/PC backplane plate on it was the one sticking out of the left side of my DuoDock's lid for many years.
It's not hard to come up with the right configuration.
