The way I understand it, there are two types of cables: 80 and 40 wire
versions. Any 80-wire IDE cable is equivalent to any other, discounting
the construction quality.
According to http://www.mathercomputers.com/supportbb-fresh.html, you may
in some cases find problems using the 80 wire cables with UDMA33, so you
are safer using 80-wire cables for 66 and 100, and 40 wire cables for any
old hardware you have. I imagine the backward incompatibility has to do
with the lower impedance of the 80 wire cable.
