Vintage Wang 144 T Electronic Calculator Nixie tube display. A beautiful shelf piece or Nixie tubes for a project. Extremely Rare piece of marksmanship. Tubes look to be in good condition, albeit untested. The display of the 144 is integrated into the upper part of the cabinet of the machine. The display consists of fourteen Nixie tubes soldered to a circuit board that is mounted in a sturdy cylindrical metal housing. A tinted plastic sheet is mounted in front of the cylinder such that the Nixie tubes shine through it. There are large machined aluminum "thumb wheels" at each end of the display cylinder which allow the viewing angle of the display to be adjusted to the user's preference. The Nixie tubes have 1/2-inch tall digits, which are easily read from quite a distance. The display is multiplexed, but at a slightly slower rate than some of the other machines I've come across with Nixie displays, such that a slight "shimmer" is visible. The left-most tube contains only a "+" and "-" to indicate the sign of the number in the display, and the remaining 13 tubes contain the digits zero through nine, and a right-hand decimal point. Numeric entry proceeds left to right, but once a number is "entered", it is positioned in the display such that it is right-justified based on the decimal point selection setting. Leading zeroes are blanked. read more
