Written by Accutron on 2017-03-21  

Introduced in 1969, the side-viewable B5440 is a later example of Burroughs' Nixie tube product line. In addition to the B5440 base part number, Burroughs manufactured a range B544x variants, including the B5441 with dual decimal points, the inverse-mounted B5445, the B5441 and B5448 symbol displays, and the B5440A which lacks a top nipple.

The example pictured here is a second-source NL-5440, manufactured by National Electronics.
