The GC10/4B is a cold cathode counting & display tube. In use the discharge would cause one of the cathodes to glow and its position would indicate a number. The cathodes and guide electrodes are all arranged around a central common anode. The orange glow of the neon discharge allows the position of the discharge to be seen and thus functions as a indicator. An output pulse is achieved once for every ten input pulses allowing cascaded devices to form the digits of a decade counter.
To advance the display the inter-cathode pin electrodes would be energised, the article above gives a detailed description of how to operate these tubes. The discharge would walk to the next cathode using the pin as a guide.
The end window envelope is 28 mm in diameter, and excluding the IO base pins, is 86 mm tall.
