| Burroughs Class 1 |
 |
| "This Burroughs Class 1
was one of the most spectacular adding machines made. It was quite imposing at 19"
deep, over a foot tall and more than 63lbs. It had beveled glass walls on 3 sides allowing
viewing of the rocking segment mechanism. (The segments and key stops are seen clearly in
the front window.)" David Hicks. |
