| On November 27, 1957, IBM announced the 087 collator. It was
the one of the first two products developed by the company's
laboratory in Rochester, Minn., as a redesign of existing collators
already built in Rochester.
The 87 collator compared alphabetic, numerical, and special
character data punched into cards while performing many card
filing and selection operations. It simultaneously could feed
two sets of cards, merging the matched cards and selecting
unmatched cards. In addition, the machine could check the
sequence of the primary file of cards. The 87 operated at
speeds of 240 to 480 cards a minute.
IBM withdrew the 87 collator from marketing on September
7, 1978.
