- Description
- This gray metal instrument checked the "registration" or alignment of a card punch. Its surface is marked and numbered like an IBM punch card, with 80 columns of numbers. A sample punched card, held in place by three protrusions, fit over the surface and was compared to the rectangles below. Machines out of registration could then be reported.
- A mark on the bottom reads: MFG. BY I.B.M. Another mark there reads: GAUGE CARD FACE UP.
- The device fits in a brown cardboard envelope that is covered with cellophane. A mark on the envelope reads: 450550.
- This is a gauge for an IBM 5081 punch card and a related card punch. It was used at the University of Pittsburgh in Professor Robert A. McConnell’s research on parapsychology.
