Ken Koeneman was stationed at Kincheloe AFB from March, 1966 to October, 1968 in the MA1 mockup on the really old computer system before transistors. The conversion to IRAM was just starting when he left the Air Force in late 1968. This is a sewn 438th FIS logo on a shirt he purchased at the 507th CAMRON reunion held in the early 2000's.
