FBE ZCLK Clock Board for Heath / Zenith Z100 or Z120

Description

This is kind of an oddity. It was designed for the Heath / Zenith Z100 or Z120 computers. Those were very capable machines, but they were not 100% IBM-PC compatible. They did not have any way to automatically set the time or date.
This small board mounts on the motherboard. It uses a standard 2032 battery. I do have some documents and an assembly language clock utility program for it which will be included.
