For sale is this surplus used salvage. They were pulled from TTI 1100-series transmission test sets which were functional at time of being scrapped. As noted in the title; board has three Burroughs 8423 / B-6091 nixie tubes (numbers), one B-6034 tube (+/- sign), and three TI SN74141 drivers as well as some other components.  Boards measure approximately 9 X 3-3/8 inches.

Board world be very nice for use as-is in a clock project.

These are used surplus salvage - in good physical condition but electrically untested.

NOTE: I have three of these boards, they are the same electrically, they have the same parts, but they differ slightly in appearance (the shade of green of the circuit board material, the color of the lettering on the tubes, etc.) You are getting one of the three (unless you buy more than one).
