|Burroughs BD-301 / 6703
|Written by Accutron on 2007-03-26
The BD-301 is an early shielded model with a large envelope and magnet, similar to a shielded 6700. It should be noted that at least one BD-301 print style includes a 6700 dual part number. This is odd, because the electrical characteristics of the 6700 and BD-301 are similar, but not identical.
