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,
