Today's #Panaplex display is the Heathkit GC-1005 digital clock

But to carry on the #Panaplex theme, how about two digital multimeters: Datron 1057a on the bottom and Data Precision 3500 on the top. Data Precision has a red filter over the neon orange Panaplex displays

After a positive response to the #Panaplex photos, here's a #Nixie tube instrument: the Fluke 8120A Digital Multimeter, introduced in 1972

I did try “ringing” the Addmaster 01 Hotline number – but strangely no one answered. So I repaired and restored this vintage 1972 Addmaster calculator myself. It uses an early gas discharge “Panaplex” orange display. #VintageElectronics #VintageCalculator #Panaplex
