EPROM Replacement and Programming

Larger updates have too many changes to fit in the update portion of the EPROM. An update with this many changes requires an EPROM replacement and reprogramming procedure.

The EPROM is removed and replaced with a new basic state EPROM. The latest software is programmed into the new EPROM providing a data set that has the latest available software.
