HP21MX lurkers - question

My 7970E just came in with a 13183 controller - offline checks work great!

Plus the 7970E came with another 21MX E series (my fourth :) ). Here's the
question... all my 2113B's and 2113E's have TWO ribbon cables going to the
front panel (operator panel). My 2108A and 2109B only have one cable to the
front panel. Most of my 21MX docs are for the M series and they only talk
about one cable going from the system PCA to the front panel.

Anyone know what the reason is for the second cable (what it does), and more
importantly under what circumstances is a second cable needed? I'm hazarding
a guess that it's anytime there's memory feature addons (M.E.M., Parity,
Fault control, etc.).
