The '''IBM 407 Accounting Machine''', introduced in 1949, was [[List of IBM products#Unit record equipment|one of a long line of]] [[IBM]] [[tabulating machine]]s  dating back to the days of [[Herman Hollerith]]. It had a card reader and printer; a summary punch could be attached.  Processing was directed by a [[plugboard|control panel]].

The 407 was the central component of many [[unit record equipment]] shops which were the mainstay of IBM's business at the time. It could print digits, letters and several special characters in any of 120 print positions, spaced {{convert|0.1|in|mm |disp=x| apart (|)}}.

IBM stopped marketing the 407 Accounting Machine in 1976.<ref>{{cite web |url= http://www-03.ibm.com/ibm/history/exhibits/vintage/vintage_4506VV4007.html |archive-url= https://web.archive.org/web/20070101062514/http://www-03.ibm.com/ibm/history/exhibits/vintage/vintage_4506VV4007.html |url-status= dead |archive-date= January 1, 2007 |title=IBM 407 accounting machine |work= IBM Archives |publisher= IBM}}</ref>
