BA-16 Dekatron Adder (Unknown Mfr.)  
Written by AnubisTTP on 2011-01-29  


This device is a plug-in single stage adder utilizing a 'Dekatron' glow transfer counting tube for display and counting functions. The installed tube, a Baird Atomic 6476A, is a 4kHz neon filled selector which brings each of its ten outputs out to a separate pin. Each output pin is brought to a plug connector on the back of the device, allowing the position of the counting tube to be read by external devices. This module also contains a single an RCA 2N270 transistor, a rather out-of-place component to reside in a tube based counting module.
