[ale] OT: scsi cables

Looking closely at your pictures your PCI card is certainly a HD50
female connector (which would need the male cable end) but your device
connector actually looks like a micro Centronics MC50 not an HD50.  I
say that because it has exposed gold fingers (not pins, but fingers) and
a wide slot through the center.  That's exactly how a Centronics (think
parallel printers but smaller) is constructed.

You either need to find an HD50 to MC50 cable (possible but not easy) or
get an HD50 to MC50 adapter to adapt a normal HD50-HD50 cable or
MC50-MC50 cable or even having to go the intermediate route of using a
standard Centronics CN50 or D-shell 25 to MC50 cable somewhere in the
middle.
