Note:
If you are connecting a combination of both 8-bit and
16-bit devices to the external connector of a channel, you
must connect the 8-bit devices
after
the 16-bit devices; once
you step the cable down to 8 bits, you cannot step back up
to 16 bits. You will also need a 68-pin-to-50-pin connector to
attach the last external 16-bit device to the first 8-bit device.
