Time-Recording Business Doesn't Compute
The recoding division of IBM churned out Daily Dial Attendance Recorders such as this model in the 1930s. Employees turned the dial to their employee number and punched in. The device came in three sizes--50, 100, or 150 employee--and attendance was logged on a single or double printout drum. The time recording business was sold in 1958.
