Does anyone have a data sheet on an AMI S1427A clock chip? I have this Pernicka Corp 'Model 100-C' panel-mount clock (S/N C008). The clock itself is self-contained - runs off of a 9V battery, has two switches for setting the time and date, and is set in a nice round panel-mount housing. The PCB has just the chip (with a date code of 7728), 3 diodes, 2 resistors, 2 caps, a crystal and a trimmer. The S1427A drives a 4-digit unbuffered LCD panel. Thanks for any pointers, -ethan
