Burroughs 4021L Nixie Tube  
Written by AnubisTTP on 2006-11-06  


This Nixie tube ranks as one of the smallest circular envelope displays ever made; the digits are a mere 8 mm high. This model of tube was made in both standard pin and flying lead variants; the flying lead model is shown. The 4021 can display the digits 0 through 9, with no decimal point.

One of our samples is still mounted in its Lucite store display. It is hard to imagine a time when you could walk into a store and see an array of Nixie tubes on display like a row of blenders at Wal-Mart.
