Isn't that the DoD designation for a PDP-8?
No. It means "general computer thingy", basically. It is a very vague
nomenclature. Previously, computers tended to get lumped into the
extremely vague AN/*SQ category.
I guess an AN/UYK-43 is a VMS-based 32-bit computer,
the AN/UYK-20
has core memory, the AN/UYK-64 is somehow DG compatible. Not sure
about any other models.
Some, no doubt, are pure military designs, some are militarized
commercial models, and some are just plain commercial types with no
militarization.
