Английская Википедия:IBM 101
The IBM 101 Electronic Statistical Machine, introduced in 1952,[1] combines in one unit the functions of sorting, counting, accumulating, balancing, editing, and printing of summaries of facts recorded in IBM cards.
The 101 could sort cards based on multiple columns. For example, if a card had multiple 3-column test scores, the 101 could be wired to sort into pocket 0 those cards with no scores over 090, into pocket 1 those with one score over 090, and so on; logic limited only by the number of relays available.
A. Ross Eckler suggests the development of the 101, with functions similar to earlier multicolumn sorters and unit counters developed by the Census Bureau, "was apparently a direct result of the transfer to IBM of Lawrence Wilson, who had served as chief of the Census Bureau's Machine Tabulation Division".[2]
Functions
The following operations may be performed at the rate of 450 cards per minute:
- Sort IBM cards into numeric or alphabetic sequence
- Arrange cards into a desired pattern
- Check cards for consistency of coded information
- Check the accuracy of sorting
- Search cards for specific facts or combinations of facts
- Count cards for as many as 60 different classifications
- Print reports in final form on one or two printers
- Print group identification
- Print a check symbol on each line of a report to indicate that totals printed on that line cross-check
- Summary punch totals when one or two summary punches are connected to the 101.[3][4]Шаблон:Rp
The operation of the 101 is directed by the use of a removable control panel.
