Dg

The DG printer warns the user when the batteries get low, after six to eight hours of normal use, or when paper and ribbon are running out.

At the time, DG was a player in the multibillion-dollar minicomputer market, part of the late-'70s "Massachusetts miracle" of high tech development.

In the end, DG captured its share of commercial distributed-computing sales, partially through its aggressive selling approach and partially through its technical ability to attract high-profile designers of the most elegant minicomputer systems, like Southern Railway.
