Dialco Single Digit LED Module (Unknown P/N)  
Written by AnubisTTP on 2009-08-08  


Manufactured by Dialco, this archaic-looking device is an early example of a single digit LED display module using a tiny FND-10 LED display. An attached PCB includes a 7448 BCD to 7-segment decoder and current limiting resistors. FND-10 displays are so small as to be practically unreadable; in an attempt to counteract this, Dialco has mounted a large removable magnifier on the front of the module.
