IBM 101

The IBM 101 Statistical Sorting Machine is a statistical translation machine that combines in one unit the functions of sorting, counting, accumulating, balancing, editing, and printing of summaries of facts recorded in IBM cards. It was a mid 60's replacement machine.

Functions

The following operations may be performed at the rate of 450 cards per minute:

• Sort IBM cards in numeric or alphabetic sequence
• Arrange cards into any desired pattern
• Check cards for consistency of coded information
• Check the accuracy of sorting
• Search files of cards for specific facts or combinations of facts
• Count cards for as many as 60 different classifications in one run
• Add two 5-digit amounts punched in IBM cards to accumulate two 8-position totals; or add one 9-digit amount to accumulate a 12-position total
• Print results in final form on one or two reports of convenient size
• Print group identification
• Print a check symbol on each line of the report to indicate that totals printed on the line cross-check
• Summary punch totals when one or two summary punches are connected to the 101.

The operation of the 101 is directed by the use of a removable control panel. Exit hubs (impulse emitting) on the control panel were wired to entry hubs (impulse accepting) for the task to be done.
