B7971 x8 Display


The Cogwheel Circuitworks B7971 x8 Display is a modern implementation of a large format Nixie-based alphanumeric display. Based around (8) Burroughs B7971 display tubes from the early 70’s,  this system finally provides enthusiasts with a way to activate their B7971 collection.

The display kit consists of a driver board which is available assembled and tested, and unpopulated display boards which hold 4 tubes each. Other parts including the custom enclosure can be ordered directly from the suppliers. A step by step guide details how to acquire all the parts to complete the display. All you supply are the tubes.

If you have the tubes, Cogwheel Circuitworks provides an easy,  DIY recipe for you to implement the display.
