Commodore C112  
Written by Accutron on 2016-03-19  

The Commodore C112 is an early LSI calculator manufactured by AMI's Unicom calculator products unit. The C112 is a 12-digit four function machine with an AMI two-chip LSI chipset, and a display constructed from somewhat unusual single-digit Futaba VFD tubes. Unlike most numerical segment displays, the Futaba tubes used in the C112 have extra vertical segments which allow for more natural represntation of the '4' digit.
