The term Legacy is used to describe any old technology that is still in use. For example, NASA uses equipment from the 1970’s still, because it still works. The old adage is true; if it aint’ broke, don’t fix it.
The same holds true in industry; there is no point in replacing a million dollar machine simply because it is outdated (so long as it still works). One of the common problems with working with legacy equipment is that repair or replacement parts are either rare or non existent, and many modern products will not interface with legacy equipment properly.
Monitech has solved that problem; our displays are specifically designed to work with legacy equipment.
