AN/UYK-20

PO1 William "Chip" Nagel The UYK-20 was a solid computer, used for many different systems. On my first two ships, it was used for NAVMACS. I don't remember how to troubleshoot one anymore, because the last time I had to was is "C" School for training. Never had to do real troubleshooting on either ship except to replace a power supply once. Pretty sure each UYK-20 were on their second hull.
