Hi The Beehive was one of the best terminals I'd ever used. The one that Intel used ( and painted Intel blue ), used Cherry Hall effect switches for the keyboards. I only saw one of these switches go bad and that was because the keyboard had a heavy object dropped on it ( drive box ). It broke the ceramic that the Hall effect device was on. This keyboard had the best feel of any keyboard that I'd used before or since( around '80 ). How may out there have problems with other mechanical keyboards ( I know I have a few flaky ones ) and wish they'd used the robust Hall effect keys? Dwight give it away. I finally tossed it in the trash.
