What's "behind" the "open.jpg" panel - have you opened it further to see the

>From a manual: "The AN/UYK-20(V), is a general-
purpose processor designed to meet the requirements
of small and medium processor applications in
shipboard or shore military facilities. The processor is
used in the CUDIXS, NAVMACS, SSIXS (shore
installations), and TACINTEL subsystems."
