1666s are known as AN/UYK-64. Nitpick: the Rolm 1600s are not really avionics machines, although certainly quite a lot were put in aircraft. The military put them on land and ship installations, thus the "U". If they were primarily for aircraft installations, they would have been "AN/A**" and not "AN/U**" (and also not so freaking heavy!). -- Will
