Some old microwave stuff came into the radio museum lately, probably 60/70s vintage, amongst which was a piece with a "Control Data - TRG Division" label on it. Control Data was even imprinted on the waveguide adjustment micrometers. Idle curiousity, but anyone know how CD was involved with microwave waveguide componentry, or what the TRG Division was? (Chuck?) I didn't know CD branched out into anything beyond computing.
