The 80 conductor 16550A cable might be too short. Also, it might be keyed
the wrong way even if it was long enough. The 16550A cable polarization tab
is keyed pin 1 to pin 1, while the 16500B / 16500L/H cable might be reverse
keyed between the two ends. I'd have to pull the lid off of a 16500B to
check.
